Still catching up! Sunday was a much better day than I had expected and in the afternoon there were lots of damselflies out and I saw my first downy emerald dragonfly of the year. There are two very common blue damselflies at Blashford Lakes, one, aptly called the common blue damselfly has males with a black lollypop mark on the first abdominal segment.
The azure damselfly is as common but the males have a square “Y” on the first abdominal segment.
There are several other damselfly species as well, the largest is the very distinctive beautiful demoiselle, which favours flowing water and streams with stony substrates.
With better weather the dragonflies are starting to emerge, although I have not seen many adults yet, but the pond near the Centre has lots of exuviae, the nymphal exoskeleton left behind when they emerge from the water. I counted at least 10 around the pond at the end of the day on Sunday. I think all were of emperor dragonflies.
We have had nesting mute swans on Ivy Lake this year and they have eventually hatched, but only one cygnet, perhaps they are a young pair, at least it should get lots of care.
Emptying the moth trap this morning revealed a beautiful garden tiger moth, which was definitely a treat to see. When disturbed they display their orange hind wings with blue-black spots, the bright colours acting as a reminder to predators that they are unpalatable.

The larvae of the garden tiger moth are large, black and covered in long, dense, black and ginger hairs, giving them their name the ‘woolly bear’. They feed on stinging nettles, dock leaves and a variety of garden plants. They can be seen from August until the following June and are often seen moving rapidly across bare ground when fully grown so are a good caterpillar to keep an eye out for, although it is best to leave them to it if you do see one as the hairs can irritate.
When the sun is shining the pond is still a brilliant to spot to look for dragonflies, with common darters often resting up on a chosen spot and both brown hawkers and emperor dragonflies hawking overhead or egg laying:

There are still plenty of damselflies around and I managed to photograph this pair of common blue damselflies mating. The male is blue and the female is a more camouflaged olive green colour:
Common blue damselflies mating
The male dragonflies and damselflies have two pairs of hooks at the tip of the abdomen which they use to grasp either the neck (in damselflies) or head (in dragonflies) of the female. Pairs can often be seen flying together in tandem and shortly after capturing a female they will mate and form the ‘wheel position’ seen in the image above. Some species remain coupled for several hours amongst vegetation whilst others, like the chaser dragonflies, couple briefly for just a few seconds. Following mating the female is ready to lay eggs.
There are also still plenty of butterflies on the wing, including this common blue which was outside the front of the centre earlier today.
On Sunday we held another of our online Young Naturalist catch ups where we expanded on the last session delivered by Owain from Amphibian and Reptile Conservation and discussed all six native reptiles. We were treated to some fantastic photos by Kimberley, taken on her phone, of a very friendly male sand lizard she had encountered whilst walking her dog at Dewlands Common in Verwood.

I used to visit Dewlands Common regularly when employed by East Dorset District Council so it is great to know they are still present on the site.
Will also shared some photos he had taken, including a lovely photo of a wool carder bee on lamb’s ear (Stachys byzantina). We had been hoping the lamb’s ear in one of the planters outside the Education Centre would attract wool carder bees as they will scrape hairs from the leaves to line and seal the brood cells in their nests, but sadly there has been no sign of any.

Will also shared a photo of a small skipper butterfly which was taken up on the Laverstock Downs, a gatekeeper which he had photographed at Horatio’s Garden at Salisbury Hospital, and an abandoned robin’s nest in his bird box at home – the robin’s had for some reason moved elsewhere.
We also looked at the moths in the light trap, where the highlight was this very fresh looking Sallow kitten:
Finally regular visitor and volunteer Phil shared this photo with us of the Osprey which visited on the 16th July. It was only here on that day, but did spend quite some time sat on the perch out on Ibsley Water and Phil was able to get a photo from a distance. I was on leave that week so completely missed it!

Earlier in the year little did I know that when I locked up and left Blashford, somewhat appropriately as it happens, on Friday 13th March, that I would not be back until the 2nd July, thanks to a cocktail of a poorly child with a high temperature having to stay off school, subsequent quarantining of myself and family, lockdown and, later, furloughed leave.
A lot has changed in that time, at home, in the UK and across the World, for the Trust and, specifically, for Blashford Lakes.
Any regular readers of the Blashford Blog will know how Bob continued to manage and warden the site throughout lockdown, monitoring and dealing with the affects of ash dieback on the woodland despite, or in-spite, of the restrictions that lone-working imposed and his having to deal with the impacts that “cov-idiots” including poachers, dog walkers and cyclists were having upon the reserve and the wildlife.
As lockdown restrictions were eased he was joined by Tracy and they worked hard together to make and adjust to new socially distanced working procedures and hygiene arrangements whilst planning how the nature reserve might most safely be reopened to the public.
I for one am very grateful for all that they did and I am sure that our visitors are too, albeit that many won’t know that they are, or should be!
I returned to work from furloughed leave on 1st July, worked from home on that first day and returned to Blashford itself on the 2nd to reacquaint myself with the site and acquaint myself with new ways of working.
The site itself is much as it always was, although now displaying an awful lot more directional signage to aid visitors around the new one-way circular walking routes and with more of Tracy’s educational and insightful mini-interpretation notices which highlight particular aspects of wildlife as you explore the nature reserve.
The insects have been fabulous, none more so that the clouds of common blue damselflies which were particularly in evidence when I first got back at the beginning of the month.
The wilder areas around the dipping ponds as well as the relatively recently (last Summer) created ornamental raised flower beds and wildflower turf around the Welcome Hut at the front of the Centre have been, and are, full of insect life. Indeed our butterfly survey volunteers are finding that although the northern transect is doing well the southern transect is generally quite poor this year – with the exception of that area around the Education Centre.
One of the highlights of returning to work has been being able to view the moths attracted to the light trap over night, although always tinged a little with sadness that this summer we have not been sharing the same with our school group visitors:
The bird hides remain closed and are not set to open as normal anytime soon so glimpses of the lakes are infrequent and few but the view from the Ibsley Water viewing platform at the back of the main car park remains open and does still give a fantastic, if distant, view of that lake – and indeed it was from there that a number of visitors enjoyed views of an osprey perched on the perch placed out in that lake with just that purpose in mind. The sweet honey like scent of the creeping thistle which is growing in profusion there, alongside other fantastic nectar sources like ragwort and teasel is pretty special too:
So all in all, although the hides remain closed, there is still plenty of wildlife to see and you never know, you might get lucky and see something more unusual like an osprey, or, as other visitors have reported seeing on different days over the last couple of weeks, Blashford treats like kingfisher or treecreeper, or slightly more unusually, an otter or a family of stoats.
And visitors we are getting; plenty of regulars just like the “old days” before lockdown, but also lots of new visitors. Since restrictions eased further and holidays were allowed we’ve seen a lot of families and visitors new to the nature reserve on their holidays but we are also continuing to welcome local visitors who have and are staying close to home and who having done so are looking for new places close to home to explore and enjoy.
As a result the nature reserve is actually probably attracting more visitors this month than it would normally do so at this time of year and I suspect that this will continue over the next couple of months.
Tracy and I are continuing to develop the means by which we can engage with both visitors to the nature reserve and visitors, including schools, who might normally visit the nature reserve but are unable to do so at the present time.
A big step forward has been the installation of WiFi boosters outside the Centre which has not only allowed us to lead live virtual pond dipping activities (Tracy with her Young Naturalists meeting and myself with the Year 1 and Year 2 classes at Ringwood Infant School), but which will also enable us to offer other live virtual meetings, including “mini-beasting” or emptying the light trap for example.
Another benefit of the much improved WiFi has been our being able to re-open the Welcome Hut on an occasional basis, at least for now.
As mentioned earlier in this post, we are seeing lots of new visitors, but with the Centre and Welcome Hut closed and our Welcome Volunteers still stood down at present, there often is not someone available to provide assistance or guidance when required.
The improved WiFi coverage means that we can log on to the Wildlife Trusts remote desktop and continue to work on office and admin work from the Welcome Hut while being on hand to greet and provide assistance to visitors as needs be.
There are a number of benefits to this new working environment, not least of which is that it is a very pleasant place to work – with the doors fully opened and side windows ajar there is a lovely natural “air-conditioning”, the sound of bird song with an accompaniment of Roesel’s bush-cricket and grasshopper from the adjacent wildflower “meadow” fills the air and there is a lovely view of the tree’s around the Centre car park. Of course if anyone needs assistance we are there to help – and, as an added bonus should any further incentive to work out there be required, although it’s a bit early to be sure that it is a pattern and not just a coincidence, visitor donations seem to have gone up since I moved “office”.
This latter point is actually really important – the Wildlife Trust relies on its income from membership contributions as well as donations and at Blashford we especially rely on donations to help fund all elements of our work, from administration, to conservation, to education to access repair and improvements. Our income has been hit hard with none of the donations from group visits that we would normally receive throughout the summer, nor the usual donations from our “every day” visitors, despite there being more of them in recent weeks. This is, in part at least, because fewer and fewer people are carrying or using cash in our post-lockdown world. Bob recently made up some new “donation ask” signs with a QR code that visitors can use to make a donation to the Trust electronically and this too may have prompted more visitors who can to make a cash donation during their visit.
Time will tell whether it is my welcoming face, the new QR code or something else which will help our coffers over coming weeks!
On Sunday we had another of our fortnightly Young Naturalist catch ups, and it was great to hear what the group have been getting up to. Will had been down to the Lymington and Keyhaven Marshes and shared some photos from his walk, including one of an avocet with chick.
Thomas and Alex had been for a walk at Iping Common, a Sussex Wildlife Trust reserve, and had seen Silver-studded blue butterflies, a glow worm larva, a bloody-nosed beetle and a pill millipede.
Harry talked to us about the bug hotel in his garden which he built six years ago and is very popular with the spiders and Poppy had also sent me a photo during the week of the female broad-bordered yellow underwing moth which had emerged from a pupa she had found in the garden. Last time we met online she had shown everyone the pupa wriggling and we had guessed at Large yellow underwing, so weren’t far off!

Sadly Saturday night was so windy we didn’t have a huge number of moths to look at, despite Bob running both light traps, but we did have a dozen or so to study under the digital microscope. The group are getting quite good at identifying a few we either catch more regularly or stand out, such as the Spectacle moth or Buff-tip. The most exciting was this lovey Purple thorn, which was very obliging and posed for some time for photos:
Nigel had put together another quiz for the group, this time on butterflies, dragonflies, other insects and some spiders they are likely to see whilst out and about and we talked through a presentation on bees, the main reason for all the bee photos I’ve been taking recently!
The group have requested reptiles and amphibians as themes for the next couple of sessions and we will run another in a fortnights time. Grass snake photos will certainly be easy, I spotted one curled up in the vegetation by the Education Centre pond Sunday afternoon:
When I arrived at Blashford yesterday a rather substantial branch had come down by the entrance so I decided to walk the closer footpaths to check everything else was as it should be.
I popped into Ivy South Hide to have a look at the tern rafts and could make out quite a few Common tern chicks, although they were difficult to count especially when an adult came back with food and they all dashed around. Closer to the hide there was a pair of Black-headed gull chicks on one of the life-ring rafts and I watched the smaller one bobbing around in the water before it climbed back on to the raft:
Black-headed gull chick
Walking back up the Dockens path I saw another grass snake, this time a young one, basking on the large fallen tree close to the mushroom sculpture. I managed a quick photo before it disappeared over the back of the trunk:
Further along the path I spotted another plant I have not noticed before, identified by Bob today as Tutsan. Tutsan is a deciduous flowering shrub in the Hypericum or St John’s Wort family, and native to western and southern Europe. Its leaves were apparently gathered and burned to ward off evil spirits on the eve of St. John’s Day and it has also been used to treat wounds and inflammation. The name Tutsan comes from the French words “tout” (all) and “sain” (healthy), a reference to the plant’s healing capabilities.
From the river dipping bridge I decided to head over to Tern Hide to have a look at Ibsley Water and see if there were any Ringlets in the area of rough grass between the pedestrian gate and car park height barrier. There were a couple flying about and I also saw my first Gatekeeper of the year, although it did not settle for a photo.
Whilst photographing the Ringlet I noticed a hoverfly, Volucella pellucens, on the bramble flowers. Also called the Pellucid fly or Large Pied-hoverfly, it is one of the largest flies in Britain and has a striking ivory-white band across its middle and large dark spots on its wings. The adults favour bramble flowers and umbellifers whilst the larvae live in the nests of social wasps and bumblebees, eating waste products and bee larvae.
On reaching Tern Hide a movement caught my eye and I noticed a large wasps nest under the roof and to the right of the right hand door. I spent some time watching them flying in and out. Bob did head over there yesterday too to take a look and shared a photo, but here’s another:
Wasps and wasp nest
Although we’re not going over there as regularly as we would have done under normal circumstances, I’m surprised neither of us had noticed it sooner given the size!
Yesterday afternoon we had a brief power outage whilst our supply was switched back from a generator to the mains, and as the sun was shining I took the opportunity to linger by the planters outside the Centre, chat to the few visitors that were passing and see which insects were visiting the flowers. Although we’ve shared a few Green-eyed flower bee photos before, they are so smart I couldn’t resist taking a few more photos of them when they either rested on the planter edge or paused for long enough on the vervain.

I also spotted an Alder beetle on the lavender, a bee enjoying the astrantia, a Large white butterfly on the verbena and a mint moth.

The mini meadow by the Welcome Hut is also still really good for insects, with Thick-legged flower beetles, hoverflies and Small skippers enjoying the remaining ox-eye daisies, yarrow and ragged robin. The hoverfly could I think be a male Long hoverfly, Sphaerophoria scripta, with its narrow body noticeably longer than its wings. The female of this species is broader.
Thick-legged flower beetle
Today has been decidedly soggier, but I did watch a butterfly fly past in the rain and there are plenty of soggy looking damselflies trying to find shelter on the plant stems:
Yesterday we had our second Young Naturalists catch up via Zoom, looking once more at the moths in the light trap using the digital microscope and also at some pond creatures I had caught out of the new dipping pond first thing.
We talked about dragonfly and damselfly nymphs and had another look at an exuvia I had found floating in the pond (the dried outer casing left behind when the nymph finishes the aquatic stage of its lifecycle), looked at lesser and greater waterboatmen and a couple of different diving beetles and a diving beetle larva, talked about what materials cased caddisfly larva use to make their cases (the one I caught was thinner and more streamlined than the one in the photo below, living in a tiny tube made of pieces of reed or leaf), talked about the feathery gills on the baby newts or efts which enable them to breathe underwater and are absorbed as they develop, and watched a whirligig beetle whizzing around on the surface of the water – they definitely have the best name out of all the pond creatures!
I didn’t get round to taking any photos of the creatures as a number were trying to escape whilst I was talking about them, so they were swiftly released back into the pond whilst volunteer Nigel chatted through the moths he had caught in his light trap at home. Here are some photos I took a while ago now, it was quite nice to go pond dipping again!

Eft or newtpole
Nigel had also prepared an A to Z of birds quiz which kept the group entertained, especially as not all of the birds were native to this country. Bonus points were also awarded for additional questions about each bird, so I think the group learnt a thing or two, including where Nigel has been on past holidays!
After a very soggy start to the day the sun came out after lunch so I went for a walk around the reserve. In the meadow I was treated to some great views of a female Black-tailed skimmer, who I had disturbed when passing but seemed content to settle again on the grass:
Female Black-tailed skimmer
Seeing dragonflies and damselflies at rest is one of the best ways to tell the two apart, dragonflies rest with their wings outstretched, as above, whereas damselflies rest with their wings held together over their abdomen or body:
Common blue damselfly at rest
I also found a Mint moth, Pyrausta purpuralis enjoying the ox-eye daisies. Although the grass and flower stems turned brown very quickly with the absence of rain, the flowers themselves are still blooming.
Mint moth, Pyrausta purpuralis
On my way up to Lapwing Hide I saw what I first thought was a bumblebee, but on closer inspection realised it was a bumblebee hoverfly.
Bee mimic hoverfly, Volucella bombylans var. plumata
This hoverfly is an excellent bumblebee mimic. There are two main varieties, Volucella bombylans var. plumata seen above has yellow bands and a white tail, mimicking the Garden, White-tailed and Buff-tailed bumblebees whilst Volucella bombylans var. bombylans is black with a red tail, mimicking the Red-tailed bumblebee.
Mimicry reduces the chances of the fly being predated because it resembles a bee. In addition, the females lays their eggs in the nests of bumblebees and wasps where the larvae feed on the nest debris and occasionally the bee larvae as well.
On my way back to the Education Centre I was lucky enough to spot another female Black-tailed skimmer, who also posed beautifully so I could take a really good look and take some more photos:

Dragonflies have amazing vision, which they use to locate and catch insects whilst on the wing. Like most insects they have have compound eyes: each eye contains several thousand individual facets, with each facet containing a tiny lens. Combining all the images from each lens makes their sight better than most other insects.
Their eyes are holoptic, which means they meet along the middle of the head and take up most of it, wrapping around the head from the side to the front of the face. In comparison a damselflies eyes are also large, but they do not meet and there is always space between them. This is known as dichoptic and can be seen on the Banded demoiselle below:
This week I have been putting out a number of temporary signs to highlight some of the wildflowers currently in bloom on the reserve, including herb robert, red campion, foxglove and hedge woundwort.
All are brightening up the woodland at the moment, but I particularly like the hedge woundwort with its hooded magenta-pink flowers. It is known more for having a particularly unpleasant smell, which from getting close to it to photograph the flowers and put the sign in I have to agree it does! As its name suggests, it was in the past used as a herbal remedy with its bruised leaves said to alleviate bleeding.
Whilst walking round I noticed a couple of other plants growing I don’t remember noticing before, possibly because this time of year is usually our busiest for school visits and as such opportunities to stop, look, photograph and identify something different are usually few and far between. I spotted woody nightshade or bittersweet growing amongst the bramble in the hedge by Ivy Silt pond, and another one growing near the boardwalk past Ivy South hide. Belonging to the nightshade family it is toxic. The flowers appear from May to September and are followed by clusters of poisonous bright red berries. The leaves apparently smell of burnt rubber when crushed, although I didn’t crush them to test this out!
Woody nightshade or bittersweet
Further along the Dockens path I found some stinking iris which has dull yellowy purple flowers. Also known as the roast beef plant, it gets its name from the smell of the leaves when crushed or bruised, which is said to resemble rotten raw beef. In the autumn its seed capsules will open to reveal striking red-orange berries, which do ring a bell.
The moth trap has also revealed a number of different moths over the last few days. On Tuesday there was a peach blossom in the trap, which is definitely a favourite with its pretty pinkish spots on a brown backgound. There was another in the trap yesterday which looked fresher:
Other highlights included a cinnabar, buff tip, burnished brass and today an elephant hawk-moth.
Yesterday I walked a bit further up to Lapwing Hide to see what was about and saw mandarin duck and a pair of kingfisher on the Clearwater Pond. Closer to Lapwing Hide there was a little grebe feeding young on Ibsley Silt Pond. From the hide I was surprised by how many birds were on Ibsley Water, as it has been fairly quiet recently. Whilst watching the swallows, sand martins and house martins swooping over the lake I realised there were more swans on the water than I had seen before and in counting them reached a grand total of 99. There could have easily been over 100 as I couldn’t see into the bay by Goosander Hide or the other side of the spit island.
There were also at least 86 greylag geese and 40 Canada geese. They must have been disturbed off the river and decided Ibsley Water was a safer spot.
On walking round to Tern Hide I saw at least four meadow brown, the most butterflies I think I have seen at any one time this year so far. This one settled long enough for a photo:
From Tern Hide I saw a distant little ringed plover, off to the right of the hide on the shingle and my first sighting of one this year. The biting stonecrop around the edges of the car park is flowering: it is also known as goldmoss because of its dense low growing nature and yellow star shaped flowers. The common centaury which can be seen in places off the edges of the footpaths and also on the lichen heath is beginning to flower. As with other members of the gentian family, its pink flowers close during the afternoon.
The planters outside the centre are still providing good views of insect life, despite the drop in temperature and absence some days of sun. I managed to get a photo of one of the dark bush crickets that have been hiding in amongst the Lamb’s ear and also spotted a ladybird larva which after a bit of research I think might be of the cream spot ladybird.

Bee, andrena sp
Today I popped briefly to the meadow which apart from the large numbers of damselfly was quite quiet. I saw one solitary bee enjoying the ox-eye daisies and also spied a female bee-wolf in her sandy burrow. I watched her for some time.
Bee in the meadow
Bee-wolf in her burrow
The damselflies have still been active on the wing despite the lack of sunshine and I managed to photograph an azure blue damselfly to the side of the path and a pair of I think common blues mating in the mini meadow by the welcome hut.
Azure blue damselfly
Today’s highlight though has to be bumping into a visitor, Dave Shute, who had come to Blashford in the hope of some bright weather and seeing a clearwing moth. He just about got away with it!
Clearwings are a group of day-flying moths that look a bit like wasps but are usually very rarely seen. As their name suggests, they differ from other moths in that their wings frequently lack scales and are instead transparent. As a result of them being hard to track down, pheromone lures have been developed to make finding them that little bit easier, and these are artificial chemicals that mimic those released by female moths to attract the males. Bob has put out lures here in the past, usually attracting red-tipped clearwing whose caterpillars favour willow, and last summer also found an orange-tailed clearwing which was attracted to a lure designed for both these and the yellow-legged clearwing.
I was lucky enough to see the orange-tailed clearwing last summer but don’t think I have seen a red-tipped clearwing before, and this was the lure Dave had bought. He had seen one come to the lure but disappear before I saw him, but whilst we were chatting another came and this time rested on a nearby bramble allowing us to photograph it, I think the sun disappearing at that moment helped!
The lures do not harm the moths, but they should only be used for a short period of time and it is best not to use individual species lures regularly at one site in one season so as not to disturb the insects too much.
It was great to see and a surprise for an otherwise rather grey and wet day, so thank you Dave!
I made the most of the weekend sunshine and spent some time in my garden, now with a refurbished pond. Refurbished in that it now actually holds water, it had been reduced to an ephemeral pond at best, an interesting habitat, but perhaps not the most appealing in a garden. On Sunday I decided to use the last of the rainwater stored in the water butt to top up the pond, trusting in the forecast rain to replenish the store. I was almost instantly rewarded with the appearance of a female broad-bodied chaser dragonfly, perching near the pond and then dipping her abdomen into the water as she laid some eggs.
broad-bodied chaser (female)
A little later there were two, chasing each other around between bouts of egg-laying and resting up in the sun. I also saw large red damselfly and common blue damselfly in the garden, making three Odonata in the garden before the end of April.
It was a weekend for egg-laying insects I watched, but failed to photograph successfully, an orange-tip laying on the garlic mustard and a holly blue laying on alder buckthorn.
holly blue female
I had not known that holly blue would lay on alder buckthorn, although I did know they used a good deal more species than just the traditional holly and ivy. Laying on my rather small alder buckthorn also puts the caterpillars in direct competition with the brimstone caterpillars when they hatch in a few days after being laid last week.
The early rush of butterflies was dominated by brimstone and peacock especially, with fewer comma and small tortoiseshell. Perhaps because of the very good weather these species seem to have declined rapidly an dare now being replaced by the whites and the first of the arriving red admiral. Small white and green-veined white are residents and typically pick up in numbers during April.
green-veined white (male)
Large white are resident in rather small numbers but bolstered by, sometimes very large, arrivals of migrants.
large white (female)
There is a bit of a race on at the moment to see who can add the next new butterfly species to the UK list. One thing is pretty certain it is going to happen and probably not very long away, in fact it may well already be here. The species is the southern small white, it has expanded from southern Europe over recent years all the way to the channel coast, under 30 miles away. The difficulty is that it is quiet similar to our regular small white, so if you want to make a name for yourself look up the differences, keep your camera handy in the garden and plant candytuft. Why candytuft? Because it is the preferred caterpillar foodplant of the southern small white. It could be you, especially if you live on the south coast, the Isle of Wight has to be a likely location, if someone in Kent does not get in first!
I will end on a picture of the most dramatic plant in my garden, the giant viper’s bugloss Echium pininana which as it starts to flower becomes a tower of bees as the flowers shoot 3 to 4m or more into the air.
giant viper’s bugloss
I have, of course been recording the species I have seen in the garden and uploading the data to the many citizen science recording schemes, something we can all do for everything from butterflies to earthworms.
I spent most of the day report writing, not an activity conducive to seeing a lot of wildlife. However at lunchtime I got out by the pond and found a male common blue damselfly tucking into a small moth he had caught. They are very aggressive predators, even if only at a small scale.
male common blue damselfly with prey
It was a good day for insects and the hemlock water-dropwort was quite busy with hoverflies and bees. Amongst the hoverflies were a couple of Scaeva pyrastri, a migrant from the continent with distinctive white comma markings.
There was little to report on the bird front today, although I did see my first flying black-headed gull fledglings of the year, they are very early and well ahead of any of the others on the reserve.
A fairly busy day on the reserve today with a steady stream of new visitors, it is always good to encounter people who are still just discovering us after all this time! I was out with the volunteers removing brambles from a warm south-facing bank which I hope will prove popular with insects and reptiles.
It seems odd to say there was not a lot of bird news when the Bonaparte’s gull was still present, but it has been here a while now and most who were keen to see it have done so by now. The first summer little gull is also still with us, otherwise migrants were a dunlin, a whimbrel and at least three common sandpiper. Numbers of swift have increased again I think, with at least 100 zooming noisily about this afternoon.
Out on the edge of the lichen heath I saw a small copper and a grey-patched mining bee.
grey-patched mining bee Andrena nitida
I only saw my first damselfly of the year a couple of days ago, I don’t think I have ever waited until May before I saw my first of the year before. My first was, as expected, a large red damselfly and today I saw a single female common blue damselfly.
common blue damselfly (female)
As you can see it is not at all blue, but it has not long hatched out and has yet to acquire its colour, many females do not get all that blue anyway.
The wild daffodil have long since ceased flowering and the bluebell are starting to go over, but the reserve’s only patch of ramsons, also known as wild garlic, is looking very fine and in full, starry flower. Half close your eyes and it looks like a firework display worthy of any New Year. I was hoping to find the hoverfly that feeds on it as it would be new for the reserve, but no such luck.
Although I had not luck with the hoverfly I did find a snail-killing fly near the Centre Pond, I think it is Tetanocera ferruginea.
Although it was a rather cool night the moth trap did catch a few species including my first pale pinion of this year, never an abundant species, I usually see only a few each year.
I had the best moth catches of the year so far both at home, where the pick was a privet hawk-moth and at Blashford where honours were shared between a small elephanthawk-moth and a scarce merveille du jour.
scarce merveille du jour
The day was warm, although not always sunny, but it was warm enough for damselflies and dragonflies to be flying. The small blue damselflies so far have mostly been azure, but the numbers of common blue seem to be increasing and both can get very abundant at Blashford in good years.
common blue damselfly (male)
I had some mowing to do in the morning in an area where we are trying to establish a grassland and prevent the encroachment of bramble, we are getting there, but it takes time. Cutting at this time or year hits the bramble hard and although it does have an impact upon annual species perennials survive perfectly well and will benefit in the long run. I only cut a small part of the area at any one time, which also helps to minimise the impact. In one of the better areas which I was not cutting I found a single bee orchid.
The management of open areas does not just involve cutting, we also graze some areas and on the lichen heath we have been experimenting with stripping off the top few centimetres of vegetation. This gets us back to the mineral, sandy gravel to see if we can combat the increase in nutrients which is slowly turning it into dry acid grassland. Looking at one of the plots today I think we may have had some success as it was well colonised by one of the areas rarer plant species , slender bird’s-foot-trefoil, a species that does not seem to like competition.
Once again today I saw a painted lady, this one flying vigorously northwards, so no picture, I did get one of the other migrant butterfly I saw, a red admiral. It was perched on nettle, the foodplant so this one might have had more of a mind to breed than migrate.

The nearest thing to bird highlight on the reserve today was a bar-headed goose, as their native range is other side of the Himalayas I think we can be sure it is an escapee or the descendant of escapees.
I got home, with time to take a quick look in the meadow…………
What’s in My Meadow Today?
I mentioned meadow buttercup yesterday and today I spotted a small yellow and black hoverfly on one of the flowers. It is a common and distinctive species and one that is probably found in gardens all over the country.

My other find was a couple of ants on a flower of common vetch, they seemed to be feeding, at the base of the flower, possibly they had made a hole to get at the nectar flow without entering the flower, as bumblebees will do to runner bean flowers, effectively taking the nectar without doing the job of pollination.
