30 Days Wild – Day 5 (The Blues and more)

I was not working on Saturday and, as the sun was shining I wanted to go out, but at the end of half-term week where should I go? The New Forest would be busy, so I headed up onto the chalk, to Broughton Down, which turned out the be a good decision. It was alive with butterflies and especially with blues. Most frequent were common blue.

There were also rather fewer Adonis blue, you can tell the difference by the little black lines that go through the white wing outline.

OLYMPUS ACAMERA

A scatter of small blue gave me the run-around and it took a while to get any sort of picture of one.

OLYMPUS DIGITAL CAMERA

Although not actually blue, the brown argus is closely related to the common blue, in fact small female common blue can easily be confused with it.

The last of the day’s blues was the holly blue, there were several females egg-laying on dogwood around the reserve.

OLYMPUS DIGITAL CAMERA

Not all the butterflies were blues, although almost all were small and often difficult to keep up with. I find green hairstreak especially difficult to find and follow, their erratic flight and green colouration mean they seem to just disappear. So I was pleased when this one landed right beside me, even if a bit of milkwort was rather in the way.

OLYMPUS DIGITAL CAMERA

Other small fast butterflies are available and skippers are certainly in this category, I saw both bare ground specialist skippers in good numbers, high on the down there were dingy skipper.

OLYMPUS DIGITAL CAMERA

Whilst in the valley there were several grizzled skipper.

Other butterflies were rather few, with only brimstone frequent, a few speckled wood, green-veined white and a couple of rather late orange-tip finished off the list for the day.

OLYMPUS DIGITAL CAMERA

Not all insects are butterflies of course, there were quite a few green pot beetle.

Hoverflies were not abundant, despite the sunshine but I did see a Sceava pyrastri, typically a migrant species to the UK.

OLYMPUS DIGITAL CAMERA

Quiet a spectacular resident species typical of species rich grassland is Chrysotoxum festivum.

OLYMPUS DIGITAL CAMERA

I had hoped to be able to identify the rather brightly marked craneflies that were quiet abundant, I even got a fair picture of it, but it turns out there are several very, very similar species and a picture is just not enough.

OLYMPUS DIGITAL CAMERA

All of the species so far were ones I had seen before, but when I sat down for a drink I noticed several tiny moths on the germander speedwell flowers, these turned out to be Cauchas fibulella, whose caterpillars feed on…. germander speedwell!

A pretty good Wild Day on a great site, I will be back.

Counting butterflies and moths…

For the past few years we have taken part in Butterfly Conservation’s Big Butterfly Count, usually incorporating it into our July Young Naturalists session. We’ve missed doing it as a group this year, for obvious reasons, although I have reminded the group about the survey and hopefully some of them will be able to take part before it finishes on Sunday 9th.

Given the sun has been shining today and you only need 15 minutes to spare, I thought I would spend a bit of time by the Education Centre ponds after lunch and see what I could spot. We have counted at this spot before, but last year we went to our wild play area where we do den building and campfire activities, so if I get the chance I might try there later on in the week.

There was an abundance of gatekeepers, I counted nine in the 15 minutes, but given they are the most abundant around the whole reserve at present that was not too surprising, and two small whites. Perhaps not the most exciting count, but all records are useful and help to build up a bigger picture. In comparison, albeit in a different location on the reserve, last year we managed 15 butterflies altogether and five species, compared to today’s 11 butterflies and two species.

I didn’t take any photos at the time, as I was obviously focused on spotting, counting and recording, but the survey does include some day flying moths and in looking closely at the wild marjoram in search of the mint moths you can quite often see, I spotted a clearwing moth. On closer inspection it was a red-tipped clearwing:

I have only ever seen clearwing moths attracted to pheromone lures before, so spotting one nectaring on the marjoram was very exciting (and a complete distraction from the butterfly counting) and although it didn’t stay still for long I was pleased to get a couple of photos.

I did also spot a couple of mint moths:

There is still time to sit back and count butterflies, all you need is 15 minutes and a sunny spot, so if you get the chance between now and Sunday 9th August it is well worth it, you never know what you might see. Details can be found on their website, along with a downloadable chart and you can also use smartphone apps which make recording your sightings even easier.

As well as watching the butterflies and moths, there were lots of bees enjoying the marjoram and I noticed a shield bug on the buddleia. After taking a photo and looking it up, it is I think a hairy shieldbug.

Yesterday morning I decided to check Goosander Hide was still secure, so headed over the road first thing. Calling in at Tern Hide, there was a lapwing on the shoreline and large numbers of Egyptian geese out on the water. Coot numbers on Ibsley water also seem to be increasing, and I saw a number of mute swans and grey herons. There were also pochard, cormorant, tufted duck and great crested grebe present.

Walking the closed footpath through the old Hanson concrete site I saw a grass snake basking on the path. I didn’t notice it until I was almost on top of it, so was too slow to get a photo as it disappeared quickly into the vegetation. A little further on I had my second grass snake sighting, this time of one swimming along the edge of the Clearwater Pond. Too distant for a photo, I watched it through my binoculars until it was out of sight.

From Goosander Hide I watched the remaining sand martins flying overhead, every so often swooping low over the water and into the nesting holes in the sand martin bank. After a few minutes a kingfisher appeared, first settling further away on the trees that have been felled into the lake, before flying closer and resting on a perch. Every so often it flew down in front of the bank, hovered in front of the holes as though it was investigating them, then returned to the perch. After doing this a few times it flew closer and perched just below the hide window, which took me by surprise and I managed to get a couple of closer photos:

After visiting Goosander Hide I headed back to the Centre, feeling I had been out for long enough and we were potentially going to be busy, and the rest of the day was spent working from the Welcome Hut and chatting to visitors. A very nice office I have to say!

Given I hadn’t made it quite that far yesterday, I decided to head up to Lapwing Hide this morning as the reserve was very quiet first thing. At the hide I was greeted by a very smart red underwing moth, which was happily settled on the door. You can just see a hint of the red underwings that give this moth its name in the photo below:

From the hide I saw Canada geese, three little grebe and a number of black-headed gulls. The reedbed just past the hide was looking lovely in the sunshine:

On my way back I followed a fox cub along the path; a really nice encounter, it would run ahead, round a corner, turn then on seeing me approach run off again. I thought it had left the path to the left, but on heading round to Goosander Hide I had a second fox cub encounter, spotting one off to the left of the path sunbathing under some branches. On spotting me it too didn’t hang around, but it was great to watch, albeit briefly.

I had a quick look out of Goosander Hide but didn’t linger, spotting two grey wagtails working their way along the shoreline and a moorhen, then headed back to the Centre again along the closed Hanson footpath.

Along the path I saw a brown argus enjoying the fleabane, the first one I have seen this year and a change to all the gatekeepers I had been spotting:

Brown argus

The moth trap has produced another couple of really nice species recently, including a very smart female oak eggar which was in the trap last Thursday morning, and a dusky thorn which was in there this morning:

By the new dipping pond this morning there was a pair of mating red-eyed damselflies. I watched them being hounded every time they settled by male common blues, but managed a couple of photos:

Finally, and last but not least, here’s a very smart species of digger wasp on one of the planters outside the front of the Centre.:

Last Sunday our Young Naturalists made a rather magnificent bug hotel in a sunny spot close to the new dipping pond. The improvement works here on the reserve resulted in a rather large number of pallets accumulating, so it was great to be able to put some of them to good use.

Bug hotel

Positioning the bug hotel

We stacked the pallets one at a time, packing them with various different materials to create lots of different nooks and crannies, including bark, sticks, pine cones, old roof tiles, bamboo, off-cuts of roof from the old Tern Hide, pebbles and sawdust. We also drilled different sized holes in some of the bits of wood.

We still have a few more gaps to fill with more pine cones, dried plant and reed stems and dry grass and I’m hoping we can add a green roof to finish it off, but we were pretty pleased with our efforts:

To make a sign, Torey and Sophie carefully broke up a pallet with Geoff’s help and some of the group had a go with a pyrography pen to burn writing and pictures onto the wood.

Sign

We didn’t quite have time to finish the sign on Sunday, but volunteer Lucy made a brilliant job of finishing it off on Monday, the bugs should be impressed!

We’re looking forward to seeing who moves in!

Finley and Percy had a go at using the various bits and pieces we had assembled to make a bird feeder:

After lunch we headed off to do the Big Butterfly Count. We decided to do ours in the wild play area where we do our den building and campfire activities, as although we had seen a lot of butterflies that morning around the Centre we fancied a change of scenery to the area where we had been working. On route we spied this Brimstone:

Brimstone

With Nigel as our time keeper, we positioned ourselves in the long grass and counted the greatest number of different species seen at any one time in our 15 minute window. We managed five species in total and 15 butterflies altogether: four Meadow brown, three Brown argus, three Gatekeeper, three Common blue, one Red admiral and one Speckled wood.

The Big Butterfly Count runs until the 11th August so there’s still time to get involved – you just need to find a sunny spot (this could be your garden, a park or in a wood) and spot butterflies for 15 minutes then submit your sightings online.

We had a few minutes to spare before the end of the session so decided to head back to the Centre via the lichen heath in search of wasp spiders, which we’d heard were visible in the patches of bramble and taller grass and rush.

Finally, we spied some Cinnabar caterpillars munching on the ragwort:

Osprey!

Just when I thought that migration was almost over we get sent this splendid picture of an osprey flying over Goosander Hide last Sunday, thanks to Jon Mitchell for sending this into us.

My best bird sighting from yesterday was a couple of turnstone on Ibsley Water, it has been a very good spring for these high Arctic breeding waders, by contrast numbers of dunlin, usually one of the most common migrant waders, have been very low.

Numbers of moths have started to increase a bit, although the nights are still rather cool int he main. Sunday night yielded a few firsts for the year in the form of common swift, orange footman and cinnabar. I also saw my first buff-tip of the year, the last fell victim to a blue tit which got into the trap.

One of the regular surveys that happen on the reserve are the butterfly transects, typically May sees a big drop in numbers as the spring species season ends and we wait for the summer species to emerge. This drop in numbers has not been as noticeable as usual this year due to a very good early emergence of small copper and the blues, in our case common blue and brown argus (yes it is a “blue” really, just not a blue one!).

common blue

Although it has not been very warm, it has been sunny, which seems to be resulting in a good season for insects, or at least for some, I have noticed that dragonflies still seem to be very scarce, although damselfly numbers appear to be picking up. Looking around the Centre area at lunch yesterday I found a lacewing larva, it sticks the husks of its aphid victims to its back as a form of concealment, or at least to make it look unappetising.

Out in the meadow I noticed several common malachite beetle, usually on the yellow flowers, many insects favour particular types of flowers, but some also seem to pick particular colours.

As it was World Bee Day, I will end with a picture of a bee, nectaring at the flowers of green alkanet at the back of the Centre, these bees seem to favour flowers of this type, also commonly seen at forget-me-not.

Camping out

At our last Young Naturalists session in July, we spent a night on the reserve, exploring Blashford and the surrounding area late in to the evening and early in the morning. It seems like a really long time ago now, but hopefully this blog is better late than never…

After arriving on the Saturday morning we got straight on with setting up our camp, using old army ponchos to make dens to sleep under and whittling pegs out of willow.

We then headed to the back of the Education Centre to sit by the pond and butterfly spot as part of the Big Butterfly Count. The Purple loosestrife proved to be very popular with the butterflies and we saw a large white, numerous small whites, a green-veined white and brimstones, along with a gatekeeper and painted lady by the bramble. We also watched the water for newts coming up to the surface and spotted a number of young frogs.

After lunch we headed up into the Forest, exploring the local Rockford and Ibsley Commons for a different view of the lakes. The bell heather was in flower and attracting lots of honey and bumble bees.

We paused for a while at the bridge over the Dockens Water, exploring this stretch of the river and taking a closer look at some of the plants before heading up on to the Common for another view of the reserve, this time Ibsley Water.

On arriving back at Moyles Court we paused by the ford for a paddle, although Jorge got wetter than most!

Walking back along the Dockens we spotted this fabulous Chicken of the Woods fungi growing on an old log:

Chicken in the woods

Chicken of the Woods

Arriving back at the Education Centre, it was time to empty the light trap from the night before so we could re-set it for the Saturday evening and we also set some mammal traps to see if we could catch any of our smaller resident mammals.

It was then time to think about food and the group did a great job of chopping the ingredients before tucking in to healthy wraps toasted over the fire followed by slightly less healthy popcorn and banana stuffed with chocolate and mini marshmallows…

Lysander had also very kindly bought some of his left over Cadet rations to share with the group, cooking them through using his stove. Whilst not all sampled his food, we were pleasantly surprised by how nice it tasted!

After eating we headed off on a night walk in search of bats, picking up pipistrelles on the bat detectors in the woodland and near Ivy South hide.

After convincing the group to get up bright and early on Sunday morning, we roused them at 5.30am and headed off up to Lapwing Hide for some early morning wildlife spotting.

It was lovely and peaceful to be out on the reserve so early, and whilst we didn’t spot anything out of the ordinary we had a good wander and worked up an appetite for breakfast which we cooked over the campfire.

It was then time to check the mammal traps we had put out the previous evening, but sadly although a couple had been sprung we were unsuccessful. The two light traps however gave us 31 different species off moth to identify, along with a Dark bush cricket and an Oak bush cricket:

After tidying away our camp and bringing everything back to the Centre it was time for the group to head off, a little sleepy but having spent a very enjoyable time overnight on the reserve.

Busy in the Sunshine

Sorry for the lack of posts, we seem to have been very busy and by the end of the day exhaustion has taken over. It is the time of year when there is lots of growth to cut back, bramble regrowth to cut off and nettle to remove from potential grassland areas. Today I spent the morning removing ragwort from one of the areas due to be mowed later this month and the afternoon mowing bramble regrowth from a bank beside Ibsley Water where we are trying to establish grassland. Hot and heavy work, there are times when I think I am getting too old for it! Being out in the sun did mean I saw lots of butterflies, meadow brown and gatekeeper are probably the most abundant now.

gatekeeper

gatekeper

There are also a number of summer broods out, I saw peacock, small tortoiseshell, common blue, brown argus and small copper. Possibly a side effect of the hot weather is the number of common blue that are unusually small, some as small or smaller than brown argus. I think this happens because the food quality of the plant the caterpillar was on was not good enough or in sufficient quantity for it to grow to full size.

When I had lunch I took a look at the Centre pond and there were dozens of pairs of azure damselfly pairs, egg-laying in tandem. They do this so that the male can be sure that the eggs being laid are the ones that he has fertilised. Some dragonflies do the same and others will stay hovering close tot eh female whilst she lays.

I know that I was only doing “What’s in My Meadow Today” during 30 Days Wild, but I will end with a picture from there anyway. One thing that is very noticeable as the grass has gone brown and then yellow is that some plants remain green, field scabious is one of these, which is not just green but flowering well.

The Heat Continues

After a June and 30 Days Wild which was extremely hot and the met office now tells us was the driest on record we have now hit July and things are not changing. I did see some cloud on Sunday, but all it seemed to do was increase the humidity.

The heat is making it difficult to work, despite this on Sunday five volunteers turned out and we pulled Himalayan balsam for an hour and a half, a remarkable effort. On Monday I saw removing ragwort from the areas I plan to mow on the shore of Ibsley Water.

All this heat continues to be very good for insects, the moth catch overnight on Sunday/Monday was the highest I have ever had at Blashford, one trap caught 96 species! This included a lot of micro moths, many of these are quite spectacular looking, but it is hard to appreciate what they really look like as they are so small.

Mompha propinquella

Mompha propinquella

The one above is actually quiet common and I see it fairly regularly. I did catch a few new species for the reserve including a chalk grassland species that feeds on marjoram, a plant which does grow in the gravel near the building, so perhaps it was a local rather than a wanderer.

Acompsia schmidtiellus

Acompsia schmidtiellus a species that feeds on marjoram.

There are lots of butterflies and dragonflies around the reserve. Silver-washed fritillary are having a good year and gatekeeper are now emerging as are the summer broods of small copper and brown argus.

Brown hawker and southern hawker dragonflies are both already flying in some numbers, although common darter are still quiet few.

The picture above was my best of a few attempts at getting a flight shot over the Centre pond at Sunday lunchtime. At the same time I saw a large red damselfly that had fallen into the pond and been preyed upon by a water boatman.

When you are an insect there are many ways to die more or less everything is out to get you! There are predators and more gruesomely parasites almost everywhere. I found a parasitic wasp hunting for a beetle larva in which to lay its egg.

The needle-like ovipositor can be pushed deep into the wood, when not in use it is protected by a sheath, in the picture you can see the ovipositor in use probing almost vertically downward.

The dry weather is stressing plants and some smaller trees are losing their leaves already. Most of the grass is now brown and many species rapidly going to seed. There are still flowers out there though and one such is creeping cinquefoil.

The Blues

The last few days have seen warm sunshine by day but chilly nights, meaning it has been poor for moths but good for day-flying insects. Today at Blashford Lakes I saw my first scarce chaser and downy emerald of the year and there were other dragonflies about too with reports of emperor, broad-bodied chaser and hairy dragonfly.

Most of the butterflies that over winter by hibernation as adults are getting scarce now and spring species such as orange-tip are dropping in numbers. there are a few whites around with all three of the common species, but the highlight today was the emergence of  blues. The small meadow near Ivy North hide had six or more male common blue as I went to lock up and at least three brown argus as well, the argus is brown, but an honorary “blue” all the same..

common blue male

common blue (male), freshly emerged.

The brown argus look very like small female common blue, and the male common blues will get up to chase one if it flies by, however they quickly realise their mistake and give up. The first emergences are all males and the females will follow in a day or so. The reason for this is the same as that for male migrant bird arriving just ahead of the females. Evolution will push the males to be in place and ready for the first females to arrive, it does not pay to be late, so the pressure for males to be early is greater than that on females, who can afford to wait until they know there will be males to mate with.

The spring solitary bees are starting to disappear now, many species collect pollen from just a few plants and as these cease to flower they need to wrap up their breeding cycle. I did come across one interesting species today though, it was one of the nomad bees and the smallest species of them to be found in Britain, Nomada sheppardana.

Visiting flowers is something many insects have to do to feed, it may sound an unproblematic things to do, the flowers want to offer a nectar reward, or perhaps bribe might be a better description, to the insects that will pollinate them. However it is not as safe as it might sound, flowers can hide predators, especially the camouflaged crab spider which match their colour to the flowers they sit on.

crab spider with hoverfly

crab spider with hoverfly prey

The crab spider here matched the hawthorn flowers so well that I missed it and initially set up to take a picture of the hoverfly, only then did I see the spider!

It has not been a good year for ground-nesting birds so far this spring, with most lapwing and little ringed plover losing their eggs to predators. I suspect mammals at night as the ones nesting on the islands are doing much better. Or at least they were, on Thursday might all the black-headed gull on Long Spit abandoned their nests. Although I don’t know for sure I suspect that something swam out there and ate their eggs, probably a fox or a badger. These mammals are usually not that keen on swimming, but if they are hungry they will go to great lengths to get the food they want, I think small mammals, which are their preferred prey, are in short supply this year, which might be why they are seeking birds eggs more actively.

Despite a bad time for some ground-nesters the pair of oystercatcher are still doing well, with their two chicks growing well. They hatched on Long Spit, moved off to the shore near Tern hide and have now returned to Long Spit, this meant they were not out there on the night of the predator raid. So far the main gull colony on Gull Island shows no sign of being attacked and neither do the tern rafts on Ivy Lake.

 

Emperors

Another very hot day and a good one for insects, hot conditions allow them to be especially active as they do not need to spend time sitting in the sun to warm up as they would on a more normal English summer’s day. I saw my first Blashford silver-washed fritillary of the year, they are regular in small numbers, but never common on the reserve.

silver-washed fritillary

Later I came across a pair of brown argus, these are the start of the second generation for this species this year.

brown argus pair

Brown argus are one of the “Blues” but one that forgot this and so is not blue. The same area of grass was also hiding several stridulating Roesel’s bush-cricket, I am quite pleased that I can still hear these as they are quiet high frequency and so one of the species that slip away as we get older. If you do get to see one the pale line around the lower edge of the pronotum is an identifying character.

Roesel's bush-cricket

However the highlight of the day was none of these fine insects. After lunch I went over to Ellingham Pound to check how the common tern chicks were doing, the answer was just fine and it looks as though all seven will be flown off very soon. It is a good place to see dragon and damselflies and one of the only regular places on the reserve for small red-eyed damselfly and a quick check found one floating on some algae. I then started to look at the dragonflies in the hope of finding a lesser emperor, as there have been quite  few in the country recently and one was reported from Ibsey Water a couple of days ago. After seeing a couple of emperor dragonfly, a distinctive male lesser emperor shot past, after many attempts I got a couple of shots, not great, but I only had a 60mm lens with me!

lesser emperor male

The mainly dark abdomen with pale blue “saddle” is what identifies it. As I waited for it to skim past again I inevitably snapped other dragonflies too, when I looked at these pictures later I think one of them shows a female lesser emperor.

lesser emperor female

The lesser emperor is a migrant from the south, it used to be regarded as very rare but is getting more common, especially in warm summers and certainly tries to breed here now. It seems it is another species that is trying to colonise thanks to warming temperatures. The Odonata (dragonflies and damselflies) seem to be especially responsive to these changes with many species spreading across Europe dramatically in the last couple of decades.

Elsewhere on the reserve there were at least three common sandpiper on Ibsley Water where there was also a juvenile little egret and, at the end of the day, 3 adult yellow-legged gull. I also found that the pair of Mediterranean gull on Long Spit had managed to fledge a single chick, or at least I could only find one. Although they have nested with us before I cannot be completely certain they have raised a chick to flying on Ibsley Water previously.

Hopefully it will cool down a bit next week and I can get some of the paths trimmed, they certainly need it! I had intended to try today but it was just too hot.

Chalk downland extravaganza!

On Sunday twelve Young Naturalists joined us for a trip to Martin Down National Nature Reserve, one of the largest areas of uninterrupted chalk downland in Britain. Jointly owned and managed by Natural England and Hampshire Country Council, the reserve is home to a fantastic variety of plants and animals associated with chalk downland and scrub habitats.

Regular readers of the blog will know that part of Martin Down National Nature Reserve, Kitts Grave, belongs to Hampshire & Isle of Wight Wildlife Trust. This site is managed as part of the wider reserve by Natural England, but our volunteers do a couple of tasks there each winter – we did not visit this part of the reserve so as to avoid a busy road crossing and the car park height barrier, parking instead at the end of Sillens Lane and exploring the Down between here and the Second World War rifle range.

The weather was in our favour and we got off to a great start, spotting brown hare in a field close to where we had parked the minibus. We headed off in the direction of the rifle range, keeping our eyes peeled for butterflies and listening out for the distinctive purring of turtle dove. This stretch kept us busy with our cameras and binoculars as we saw yellowhammer, skylark, red-legged partridge, jackdaw and chiff chaff.

The butterflies also didn’t disappoint, with specked wood, common blue and large skipper settling close by for photos. We also spotted a red and black froghopper and a fabulous caterpillar, later identified as that of a drinker moth.

As we left the edge of the tree line and headed into more open downland, we saw small blue, orange-tip, small heath, brimstone, large white and Adonis blue butterflies, along with a cinnabar moth. We also spotted a number of stunning golden bloomed grey longhorn beetles, with their fantastic long and stripy antennae.

The butterfly highlight of the day though was possibly this beautiful Marsh fritillary, which was in no hurry to fly away:

Geoff took a photo of this caterpillar, which we think is that of a six-spot burnet moth.

We also stumbled across lots of tent caterpillars, so grouped because of their ability to build conspicuous silk tents in the branches of host trees. They are sociable, with many grouping together in one spot and we believe most of those we saw are larvae of the small eggar moth – the second photo may show a different species or an older instar, I’m not completely sure!

We also scoured the tops of small trees and bushes in the hope of spotting a Corn bunting amongst all the signing skylarks, a bird I’d been hoping to see! We were in luck, watching one for some time before it flew off to perch further away on another bush.

We paused for lunch at the rifle range, an excellent spot as it turned out as whilst sat on the top we watched a female cuckoo fly from bush to bush below us, sitting on the top of one for a few moments before flying back into the scrub and out of sight.

We then followed the Neolithic Bokerley Ditch which snakes along the western edge of Martin Down, defining the Dorset and Hampshire border. Possibly built as a boundary in the Iron Age, it was fortified in the 5th or 6th centuries AD against invading Saxons. We were now in search of orchids, spotting plenty of common spotted orchids and finding the beautiful burnt tip orchids.

The other wild flowers did not disappoint either and we identified yellow rattle, kidney vetch, horseshoe vetch, meadowsweet and wild or yellow mignonette amongst others. We also saw and heard stonechat, more yellowhammer, a roe doe and two brown argus butterflies.

We decided we had just enough energy and time left for one last slope in the sunshine so headed uphill, in search of a greater butterfly orchid. At the top of the slope we found these along with fragrant orchid and also spotted a five spot burnet moth.

It was then time to head back to the minibus before the showers started and we almost made it! We had unfortunately run out of time to linger for long by any of the scrub for the sound of turtle doves and the rain shower although very refreshing began to get heavier, but Geoff who was walking at the back of the group did manage to pick out their distinctive call.

We had a brilliant day, it was definitely hotter and sunnier than we had been expecting which bought out a great variety of butterflies including Adonis blue, brown argus and the beautiful marsh fritillary. We also had great views of brown hare, corn bunting, yellowhammer and cuckoo. Martin Down is a brilliant site for downland species and definitely worth a visit on a sunny day!

Back at Blashford, the two oystercatcher chicks were again showing nicely in front of Tern Hide with both adult birds also present and continuing to be very attentive. The light trap has been revealing more moth species now the nights are warmer, with highlights on Sunday including a chocolate-tip (sadly no photo as my camera seems to have momentarily malfunctioned!) and scorched wing and yesterday we had lots of light emeralds and a lovely privet hawk-moth.

Our Young Naturalists group is supported by the Cameron Bespolka Trust. Thank you to volunteers Nigel, Geoff, Emily, Kate and Roma for your help on Sunday!
