Arrivals

Although there has not been much sign of migrating birds at Blashford Lakes so far, there have been some insect arrivals. The birds at this time of the year are returning from breeding to the north, the insects, by contrast, are arriving from the south. It seems likely that there will be many more in the days to come as the high pressure builds back and temperatures rise again.

So far we have recorded a couple of lesser emperor dragonflies, but no southern migrant hawker as yet, but I am hopeful that someone will spot one somewhere on the reserve soon. The other migrant so far have all been moths. This morning the traps had silver Y, rush veneer, diamond-backed moth, dark sword-grass, Cydia amplana and Yponomeuta sedella, all probably freshly arrived from the south.

Cydia amplana, a migrant Tortrix moth that seems to be getting more frequently recorded each year.

Yponomeuta sedella

Yponomeuta sedella, this could be a migrant or a scarce local resident, it feeds on Sedum species, mainly the larger ones such as orpine, which does not grow at Blashford.

Perhaps oddly there have been very few migrant butterflies this summer, just a few painted lady and those several weeks ago now. It has also been a very lean year for humming-bird hawk-moth and convolvulus hawk-moth so far, but maybe numbers will pick up.

Just as I wrote the above I heard a buzzing sound at the window, only to find a humming-bird hawk-moth trapped inside the house!!! I have just successfully released it into the great outdoors to continue heading north.

I wonder what tomorrow will bring…………

30 days Wild – Day 10 –

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 elephant hawk-moth and a 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.

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.

30 Days Wild – Day 9 – A Migrant Arrival

Another day spent largely in the garden doing various odd jobs. Just being outside means you cannot avoid wildlife, it was not particularly sunny, but warm enough to bring out lots of bees. I have some purple toadflax in the border and it is a great favourite as a nectar source for wool carder bee.

wool carder bee

wool carder bee (male)

This is the only species of this genus, Anthidium, in the UK, they are very distinctive and quite common in gardens. They get their name because the females make the nest cells by collecting fibres from woolly leaved plants such as lamb’s ear.

I grow a lot of plants because they are good nectar sources for insects and one of the best is Cephalaria gigantea a type of giant pale yellow scabious that can get up to 2m tall. Today these flowers scored with a painted lady, judging by the battered wings a migrant, probably hatched in the Mediterranean area somewhere.

painted lady

They will breed here with the larvae feeding on thistles and emerging as adults in early autumn, these will then make a return migration southwards. This southward autumn movement had been speculated about, but unlike red admirals which can be seen heading south in late summer, painted ladies just seemed to disappear. It turns out they do head south, but mostly at high altitude, which is why we don’t see them.

Heading back inside I found a robberfly on the back door of the conservatory, I liberated it but managed to get one picture just before it flew off.

robberfly

Dioctria baumhaueri, A robberfly

They are predators, catching other flies and even small wasps in flight. They have large eyes to spot their prey and typically sit on exposed open perches, waiting to dart out and catch any suitable passing insect.

At this time of year conservatories can catch huge numbers insects, they act very like interception traps, especially with the doors open. I always leave several high windows open to give them the maximum chance of escape, ideally open rooflights if you have them.

What’s in My Meadow Today?

Perhaps unsurprisingly meadow buttercup, which really is the typical buttercup found in meadows. It has much taller flower stems than the more familiar creeping buttercup and more finely divided leaves.

meadow buttercup

I found I had one plant in my first year of managing the lawn as a meadow, but a single cut a year seems to really favour it and now there are a good few plants. In the picture you can see the brilliant yellow flowers and the extra shiny area towards the centre which acts as a mini solar reflector and increases the temperature of the flower’s centre. On the right you can see a seed head, a mass of seeds each with a tiny hook.

Back at Blashford Lakes tomorrow, I suspect I will be cutting path edges for at least part of the day, I hope it is not too warm.

30 Days Wild – Day 8 – An Early Start

I was out early doing a farmland bird survey up on the Hampshire chalk, it was calm, which is good for surveying. The low cloud got lower and lower as I was surveying and just as I was finishing it started to rain. I like surveying in a very different area from my usual haunts as it means I see species I don’t normally encounter. Visiting chalk farmland meant that yellowhammer was frequent, a bird I very rarely see these days. My previous visit had also produced corn bunting and grey partridge, missing today, although I did add red kite this time.

At this time of year an early survey means that I can get home in time for breakfast, which I did today. I was having a day off, so most of the rest of my wildlife for the day was seen in the garden.

I started with the moth trap, the pick of the day was a very fresh beautiful yellow underwing. These tiny moths regularly fly by day as well as at night and so often fly from the trap as it is opened, luckily for me this one stayed put for a picture.

beautiful yellow underwing 2

It does have yellow underwings, but they are covered by the upper-wings, however the upper-wings are beautifully marked.

The spring solitary bees have mostly finished now but the summer ones are just starting, one of these is, if I have identified it correctly, Willughby’s leafcutter bee. These bees collect pollen on brushes of hairs underneath their abdomen rather than on their legs as many species do. It is on the orange hawkweed often known as fox-and-cubs here.

During the day I saw single green-veined white, red admiral and painted lady butterflies the latter two indicating migrant arrivals.

I came across a couple of new species for the garden today, a mullein moth caterpillar that I spotted from indoors when I was washing my hands after being in the garden and, rather less welcome, a forest fly which chased my around.

mullein moth caterpillar

As the name suggests mullein moth caterpillars usually feed on mullein, however they sometimes eat other related plants such as figwort, which is what it is eating in my garden. It is another species with bad tasting larvae, which is why they can afford to perch in the open and be brightly coloured. Despite running a moth trap I have never caught the adult moth in the garden, but this is one moth species that very rarely comes to light.

The forest fly is a biting species that mostly feeds on ponies and deer, it is one of the flat-flies, which scuttle over their hosts and are very resistant to being swatted.

What’s in My Meadow Today?

For the first time thus year I have bird’s-foot-trefoil flowering in the meadow this year, for some reason it has taken some time to get established, but hopefully is now in place to stay.

A feature of the meadow from the first year has been a large population of lesser stitchwort, focus down through the grass stems and there are masses of tiny white star-like flowers.

Finally I also found a further new species for the garden in the meadow, it was a small species of chafer beetle, if I am correct it is Welsh chafer Hoplia philanthus , despite the name it is not confined to Wales having a rather scattered distribution across the southern half of the UK.

One Day, Two Reserves

I am not often at Blashford on a Saturday, but this weekend I was, I managed to intersperse catching up on paperwork with a walk round all the hides. Getting around the reserve is very pleasant but also highlights all the tasks that need planning into the coming winter season, I think an eight month winter would just about be enough!

Opening up the hides I saw a greenshank and three wheatear from the Tern hide, which suggested that there might well be migrants about and with luck “something” might turn up.

As usual the day proper started with a look through the moth trap. This contained no rarities but one unexpected moth, a very fresh dark form coronet, this is an attractive moth and one we see quite often, but it flies in June and July. If I was to get one at this time of year, I would have expected it t be an old, battered one on its last legs, not a pristine newly emerged one.

The cumulative results of my wanderings throughout the day indicated that there were indeed a reasonable scatter of migrants around the reserve. Chiffchaff were frequently to be seen, although willow warbler were many fewer than last week. In one mixed flock of birds near the Lapwing hide I saw a very smart juvenile lesser whitethroat, a rather rare bird at Blashford these days. On the south side of the main car park a spotted flycatcher was catching insects from the small trees and there were several blackcap eating blackberries.

In the early afternoon I was in Tern hide when I spotted an osprey in the distance flying towards us down the valley, it looked as if it was going to come low over Ibsley Water, but as it came over Mockbeggar North lake a large gull started to chase it and, rather than brush off this minor irritation, it gained height and headed off at speed to the south. It was a young bird and is going to have to learn to tough out such attention.

It was not a bad day for insects, I saw red admiral, painted lady, small white and speckled wood, despite almost no sunshine and there were good numbers of migrant hawker and brown hawker about. I also saw more hornet than I had noticed so far this summer and very widely about the reserve too.

Other birds of note were mostly signs of approaching autumn, a single snipe near the Lapwing hide was the first I have seen since the spring here and later wigeon, one on Ivy Lake and 4 on Ibsley Water were also the first returns that I have seen.

For a couple of years now I have been noticing increasingly large floating mats of vegetation in the Ivy Silt Pond and kept meaning to identify the plant species involved. I finally did so yesterday and one of them, the one with the rosettes of pointed leaves, is water soldier, a rare plant in Hampshire and mostly found on the Basingstoke canal!

water soldier

It is probably most likely to be here as a result of escaping from a local garden pond, but might be wild, anyway it seems to be a notable record and as far as I know it has not been recorded here before.

In the evening I went out to another reserve in my area, Hythe Spartina Marsh, it was close to high water and I was interested to see if there was a wader roost. There was, not a large one but interesting, it included 74 ringed plover, 30 dunlin, 2 turnstone, 3 grey plover and a single juvenile curlew sandpiper. In addition 2 common sandpipers came flying north up  edge and on the way across the marsh I saw a clouded yellow butterfly nectaring on the flowers of the sea aster. I also saw that on e of the juvenile ringed plover had got colour rings on its legs, however it would only ever show one leg so all I could see was a white ring above a red ring on the left leg, not enough to identify where it had come from. Ringed plover can breed locally on our beaches or have spent the summer way off in the high Arctic of Canada, so it would have been good to see all the rings.

Mothless, well Almost

Yesterday I ran a “Moth event” at Blashford, unfortunately I forgot to tell the moths and there were probably more human participants than moths! Usually late August is a good time for catching large numbers of moths, but big catches require warm, calm nights following warm settled days. What we had was a windy, mostly clear night following a rather stormy day.

Luckily the day got more settled as it went on, at least until late afternoon anyway. This brought out good numbers of insects, including as many dragonflies as I have seen this year. Around the reserve I saw several brown hawker, southern and migrant hawkers, an egg-laying emperor dragonfly and a fair few common darter. Damselflies included common blue, azure, red-eyed, small red-eyed and blue-tailed.

Butterflies were rather fewer, most that I saw were whites, with all three common species near the Centre. Out on the reserve a few meadow brown and gatekeeper are still flying and speckled wood are increasing again. Near the Lapwing hide I saw both red admiral and painted lady, perhaps indicating some continued arrival of passage insects.

The sunshine in the middle of the day brought out reptiles as well and I saw two grass snake and an adder. The adder was very fat and I suspect a female which will shortly be giving birth, since adders have live young rather than laying eggs as grass snakes do.

I have heard reports of wasp spider being seen around the reserve recently and today I finally saw one.

This is a female, the males are much, much smaller and wander about seeking the females.

I had hoped for a few different birds, following the rough weather, perhaps a few terns, but there was little change form the past week. A few extra waders were the best that could be found, 2 dunlin, 2 oystercatcher, 2 common sandpiper, 1 redshank and the pick of the day, 3 greenshank, although they only flew through. There are starting to be a few more ducks around, I saw 8 shoveler and 3 teal, but there are still no wigeon on the reserve, although they should not be far away. Away for the water looking up there were 2 raven, and single hobby and peregrine. Whilst low over the water before the day warmed there were 1000+ sand martin and c200 house martin.

Perhaps the sighting of the day for many visitors though was the female roe deer that spent part of the morning in front of the Woodland hide.

Sunny Day

As is usual on a sunny day in August the reserve was very quiet yesterday, the birds having finished nesting and most of the migrants have yet to get moving. The human visitor too mostly go elsewhere when the summer sun comes out. However the sun does bring out the insects and there was a fair showing of dragonflies and butterflies, although tempered by the fact that numbers seem to be well down this summer across the board.

The moth trap catch was quite good, but much lower than I would have hoped, but with a warm week ahead we could be in for bumper catches by next Sunday morning when I have a moth event. To whet the appetite here are a couple of pictures of regulars from the trap.

Out on the reserve there were insects about but numbers are still rather disappointing, I did see a painted lady though, a species that has not been common this year. On the edge of the lichen heath I was looking for bee wolves when I spotted what, at first I thought was a large ant, but in fact was a true-bug nymph that was trying to look like an ant.

If anything they look even more convincing from the side.

You can see the rostrum, that is the piercing feeding tube under the head that gives it away as a true bug, rather than the jaws that an ant would have.

One group of insects that do seem to be abundant are the grasshoppers. One species that still seems to be increasing is the lesser marsh grasshopper, a previously coastal species that has spread inland.

Although there were few birds of note around, there were significant numbers of some species. On Ibsley Water I counted 271 tufted duck and 355 greylag geese, the goose flock included what looked like an emperor goose accompanied by a barnacle goose and  a single hybrid off-spring.

30 Days Wild – Day 15

Up hideously early and out to do a breeding bird survey, luckily the weather was fine, although I could have done without it having rained overnight as the trees were dripping and the tall grass very wet. Still it was calm and sunny and, for mid June, a good few birds were singing. As well as the birds I saw my first meadow brown of the year, actually lots of them and also a few common spotted and southern marsh orchid and a single Mother Shipton moth.

I arrived at Blashford by ten o’clock and had a quick check of the moth trap, rather few moths but very fresh individuals of small angle shades and lime hawkmoth. However it was the trays of creatures laid out for the school pond-dipping session that caught my eye, in particular one containing a water stick insect nymph.

The sun came out briefly at lunchtime so I went out for a break from the desk and nectaring on a hemlock water-dropwort plant was a very fresh red admiral.

red admiral 2

There are quite good numbers of migrant insects about just now, there have been modest arrivals of red admiral and painted lady butterflies and huge numbers of the tiny diamond-back moth, so many that they have made the national news and it is not often a micro-moth does that! There are also lots of the marmalade hoverfly and silver Y moths, if you have flowers out in the garden you will almost certainly be able to see them nectaring at dusk.

My afternoon was spent in a meeting, but as it was still sunny when I got home I took a look in the garden and found this swollen-thighed beetle (Oedemera nobilis) feeding on an ox-eye daisy in our mini-meadow.

A summer wildlife walk

A very pleasant morning leading a guided walk today, with plenty of all round interest!

Things got off to a good start this morning when I opened up Tern Hide, with a female kestrel being mobbed by a couple of jackdaws. She has been around all of this week, mostly over the old ConBloc site and car park area, but for some reason she had really put the jackdaws noses (beaks!) out of joint today. While we were watching she gave up and settled on a post, with the two jackdaws standing guard either side of her, both swift to take off and harass her again if ever she tried to take off. Eventually they got bored and she settled to preening her somewhat ruffled feathers.

The light trap was very productive last night with 23 species recorded in total, including some of the more popular regulars including a poplar hawk moth, elephant hawk moth,  couple of buff tips and the high light, a Scarce Merveille du Jour:

Also pictured is this very aptly named figure of 80 moth:

Having looked through the light trap we walked on via the Ivy North/Woodland/Ivy South Hide/Dockens Water loop where highlights included a plethora of peacock butterfly caterpillars on the stinging nettles outside Ivy North Hide, meadow brown, common blue butterflies and a female scarce chaser dragonfly in the sweep netting meadow, female emperor dragonfly outside Woodland Hide, the regular grass snake in front of Ivy South Hide, along with a painted lady butterfly and newly hatched coot chick on the nest with mum, and a  male emperor dragonfly hawking along the edge of the water skiers car park.

Lots of peacock caterpillars!

Lots of peacock caterpillars!

Just after turning the cover towards the bridge back over the river a couple more jackdaws caught my eye. They were perched either side of a large rot hole, flying up and around it and at first I thought they were maybe coaxing outside fledglings until I realised that there were bee’s flying in and out. In fact the jackdaws were snatching these apparently tasty morsels out of the air as they entered and exited their nest in the tree. Smart birds jackdaws!

We finished off with green woodpecker and a lovely male bullfinch on the lichen heath before finishing at the centre pond for a brief glimpse of another emperor dragonfly and several egg laying azure damselflies to compliment the common blue damselflies that had of course accompanied us throughout our walk.

Shortly after one of our regular visitors and accomplished photographers spotted what might have been a young raft spider on the pond – a closer look later revealed an additional two. They are still very young and are lacking the striking yellow stripes along the abdomen, but with their greenish legs I’m reasonably confident that they are raft spiders so should provide plenty of interest over the summer if the last raft spider residents of that pond, three or four years ago, are anything to go by!

 

 

 

 

A Sunny Start

A suitably bright morning as befits a Volunteer Thursday, in fact right at the start of the day it was actually sunny and warm, so much so that I came across a painted lady butterfly in the main car park as I opened up the Tern hide.

painted lady

This is the first painted lady I have seen for a couple of months and it is interesting to speculate if it is a new migrant or the offspring of an earlier arrival. The same can be asked fo the some of the red admirals that I have seen this week, although they have been of two distinct types, either very battered and faded, possibly after a long flight, or pristine as though just hatched. The only other potential migrants recently have been a few silver Y moths, all of which have been fresh looking, below is one from the trap yesterday.

silver Y

The volunteers finished clearing and stacking the brash from the tree we felled yesterday, dead hedging it beside the path. We also cut some sections of the trunk to make seats for the education team to use with visiting school groups. Meanwhile the rest of the group sorted out the bird feeders and continued installing cable ducting. As there was a little time left at the end of the task we went  to take a look at an area we had been working in last autumn near Ivy Lake, the habitat has developed really well and it was good for everyone to see the results of their labours.

Unfortunately the sunshine gave way to cloud during the morning and by mid afternoon showers had started as the next weather system started to assert itself. Overnight we are promised another burst of heavy rain and a wet weekend to follow, not the weather to help nesting waders and common terns. I hope the quality of our tern chick shelters will at least keep them dry, but they will not help the adults as they battle to catch enough small fish to keep the chicks fed.
