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:

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.:

Camping out

This summer our Young Naturalists once again spent a night on the reserve, cooking dinner and breakfast over the campfire, setting and checking mammal traps, listening to bats, sleeping under a poncho or tarp shelter and getting up nice and early for a morning stroll up to Lapwing Hide.

Meeting in the morning, our first task was to finish off the bug hotel which we had almost completed the month before. To finish it off, we lined the roof with pond liner before adding a piece of wood around each of the four edges which enabled us to add a layer of gravel on top of the liner. We then put some sedum matting which had been left over from the construction of the Welcome Hut on top of the gravel.

Should it rain heavily, the top of the bug hotel will be protected by the liner which will stop water from seeping down and the gravel should allow a space for drainage ensuring the sedum does not become waterlogged.

The bugs have been quick to move in! We have already spotted spiders, parasitic wasps checking out the bamboo canes and our Welcome Volunteer Gail, after some very patient waiting, managed to take this photo of a Digger Wasp inside one of the tubes:

It was then time to head over to our camp area and put up our shelters for the night, using tarpaulins or ponchos and whittling tent pegs from willow. Finley and Percy had a go at making clay models – their clay men looked brilliant!

After setting up camp we gathered firewood whilst locking the hides, put out some apples and Geoff’s trail cam by the Woodland Hide to see what wildlife we could film overnight, set some mammal traps near the Education Centre and re-set the moth trap.

It was then time to get the fire going and cook dinner:

That evening we went on a night walk in search of bats and had a great time on the edge of the Lichen Heath and in Ivy South Hide listening to them on the bat detectors. We also heard Tawny owls calling and spotted a couple of constellations (The Plough and Cassiopeia) in the night sky. After a pudding of marshmallows, baked apples or bananas filled with chocolate it was time to retreat to our shelters and try to get some sleep.

After threatening the group with a four am start (they weren’t keen) we were up just after five am and after a quick snack, headed off up to Lapwing to see what wildlife we could spot.

Heading back via Tern Hide we opened up the rest of the reserve, retrieved Geoff’s trail cam and checked the mammal traps set the night before. Whilst most of them were empty, we were lucky enough to catch a woodmouse in one, which we looked at before releasing it carefully back into the bramble:

After breakfast we went through the light trap to see what had been attracted to it the night before, and this Burnished brass was definitely the highlight:

Finally, we had a look at Geoff’s trail cam and we were delighted to discover images of a jay, lots of footage of the fallow deer enjoying the apples and rather excitedly a fox:

A huge thank you to Geoff and Yvette who very kindly volunteered their time for the campout and stayed the night, we definitely couldn’t run such sessions without their help. We had a lovely time!

30 Days Wild – Day 17 – Butterflies and More

We have been doing butterfly transects at Blashford Lakes for some years now, I say “We”, what I really mean is that the volunteers have been doing them. I used to do transects myself on previous sites I have managed and thoroughly enjoyed doing them, an opportunity to go out on site for the main purpose of looking for wildlife, something I actually get to do rather rarely! In theory I have always been on the rota to help with the transects at Blashford, but as a stand-in, if someone else is unavailable. Well this week I have been called upon and as it was warm and reasonably sunny this afternoon I headed out.

It was not a classic butterfly day but I did see 26 butterflies of four species. Most notable were the five red admiral, I suspect they are new migrants as the weather is set fair for an arrival of migrants over the next day or so. Locally bred were meadow brown, common blue and speckled wood.

Whilst looking for butterflies it is inevitable that you will see other invertebrates, I saw six species of dragonflies and damselflies, several yellow-and-black longhorn beetle and lots of the larger summer hoverflies, especially Volucella bombylans and Volucella pellucens.

Not all of the invertebrates were adult, I found a vapourer caterpillar feeding in the open, something they can afford to do, as they are protected by a dense coat of hairs which most birds will avoid.

Some things I cannot identify, or at least not accurately, one such is this digger wasp, I am pretty sure it is one of them, but which one?

Some of the invertebrates were not insects at all, I came across a loose bit of bark on the ground and under it were several slugs, the familiar leopard slugLimax maximus.

This is the common native large slug in woods and gardens. However it is increasingly being overtaken in abundance by the green cellar slug, Limax maculatus. This is a species native to wood in the Caucasus area that was accidentally introduced some fifty years or so ago and is now spreading rapidly.

One plant that is oddly scarce at Blashford is honeysuckle, so I was pleased to see one of the few plants we do have growing well in magnificent, full flower.

Lastly a picture of a rare plant in Hampshire, but one that is quite common at Blashford, slender bird’s-foot trefoil, it is flowering abundantly just now.

Quiet a “Wild Day” considering I was stuck in the office wrestling with report writing for quiet a good part of the day and also out doing path clearing for part of the day.

Sunday Sun, (Eventually)

On Sunday I opened the moth trap for visitors to the reserve, the catch was actually not too bad considering how windy it had been overnight. The highlight was a micro species, Anania verbascalis, which I was only able to identify retrospectively, as far as I am aware it was new for the reserve as well as to me. Unfortunately it was very difficult to get half decent photographs as it was very dull and raining at times.

Luckily in the afternoon it did warm up and the sun came out. I had to mend part of the fence beside the sweep meadow and could not avoid admiring how good it is looking this year.

It often has a good show of ox-eye daisy, but I think it is the mass flowering of bird’s foot trefoil that really makes it look so good this year. Actually there are four different bird’s foot trefoils growing across the meadow and nearby lichen heath. In the wettest areas there is the tallest one, the greater bird’s foot trefoil, in the general grassland there is the “regular” bird’s foot trefoil, whilst as it gets drier there are patches of slender  bird’s foot trefoil and on the really dry sandy spots there is hairy bird’s foot trefoil. The rarest, at least in Hampshire is the slender bird’s foot trefoil, which seems to be having a very good year this year, with some large patches.

As I finished repairing the fence I noticed a common toad crossing the path, no doubt tempted out by the morning rain.

As the sun warmed the insects came out in force. I came across my first bee wolf of the year, in fact several on a sandy patch beside the entrance track.

These wasps capture honey bees to provision their nests, which they dig in the sand, to provide food for their larvae. I also saw several other digger wasps, I only a picture of one and so far I have failed to get a positive identification of it.
