30 Days Wild – Day 26 – So Many Moths

The night of 25th-26th June was one of the best for moths for many years, it was ideal, warm and calm. Moths fly for longer on warm nights, unlike day flying insects they cannot use the sun to warm up for flight, so are dependent upon the air temperature being high enough. This is why, on most nights the main flight will be at dusk and numbers decrease through until dawn.

I knew it would be good from the forecast and from the fact that sleep was difficult, one advantage of this was that I was awake at dawn so could go and close the trap before the birds could clear any moths that had not got inside. In my garden I run a small, low power actinic moth trap, the light is less bright and doe snot disturb neighbours, the lower light output means it catches fewer moths. I could see immediately that it was full of moths, the eventual tally was a remarkable 79 identified species, with one or two more unidentified.

Meanwhile at Blashford I had put out two traps in slightly different habitats, if my small trap had that many species how many would there be in the bigger traps? The answer turned out to be about the same, one around 75 species and the other just over 80. I suspect that some of the micro moths, which make up a lot of the catch on calm nights, get out of the trap if it is not covered and taken in soon after dawn.

Many of the micro moths are stunning to look at, if you can see them well enough! This is where macro photography and especially digital photography comes in so handy, the images can be enlarged on the screen.

My home trap did yield one new species for the garden and not a micro moth either, it was a red-necked footman. These are curious moths, I will not see any for ages and then suddenly see a whole swarm of them, perhaps 100 or more flying together around a tree top in bright sunshine.

A number of the micro moths have similar patterns, even if they are not closely related, one recurrent pattern is white with dots, this is a common pattern in the Yponomeutidae, but then crops up again int he distantly related thistle ermine, which is a Pyralid and of course in the white ermine itself, which is one of the tiger moths.

Not everything that gets attracted into a moth trap is a moth, other night-flying insects also arrive. I was very interested to catch a fine beetle that I had not seen before and which I did not remember seeing illustrated.

Diaperis boleti 4x3

When I first tried to identify it, thumbing through some general beetle books, I did eventually found it, the text said “rare in Britain”. Having identified it, at least tentatively, I looked it up on the web and found a rather more contemporary account of its status. I confirmed it was indeed Diaperis boleti, one of the darkling beetles that feed on bracket fungi, it used to be rare, but now it seems it has “become quite widespread and is locally frequent”. It is probably another species that is benefiting from a warmer climate, a reminder that there are winners and losers when things change.

At Blashford the micro moth theme continued, but with a mostly different caste, a few of which are below.

Out on the reserve the breeding season progresses, the common tern chicks are growing fast and a good few of the black-headed gull have fledged.

Back to Blashford

Last Monday I helped Bob put a couple of tern rafts out on Ivy Lake, something he had been hoping to do for a while but needed someone on site whilst he went out on the water. So when I say ‘help’, I do mean it in the loosest sense of the word as I kept an eye on him from the comfort of Ivy South hide.

The view from Ivy South hide – the spiders have moved in and the vegetation is taking over!

Luckily, two of the rafts were still on the edges of the lake, so they just needed moving out into position in the middle and securing in place. By the end of the day there were six common terns interested in one of the rafts and this number has gradually increased over the course of the week. In wandering down there today there were at least twenty either on the raft itself or flying around overhead, with a few black-headed gulls. We would usually put out more rafts but without volunteer support to make them and move them (not a job that allows for social distancing) they will have to make do with these two instead.

Whilst waiting for Bob I listened to the reed warblers with their distinctive chatty song and watched a pair of great crested grebes out on the water. I also noticed lots of newly emerged damselflies, yet to develop their full colours and markings, on the stems growing outside the hide. It takes a few days for them to develop their colouring, a useful survival mechanism as at present they are not quite ready to fly so blend in rather well with the vegetation. Lower down you could make out the cast skins or exuvia clinging on to the vegetation following their final moult and emergence as an adult.

Bob has also been busy strimming step asides into the edges of some of the footpaths, where it has been possible to do so, to create areas for people to pass each other more easily and aid social distancing when walking around.

In addition we have been busy planning extra signage for some of the footpaths and will be making some routes one way, again to aid social distancing and enable people to visit safely. Crossing the stretches of boardwalk safely will be particularly difficult, so people will be directed over these a certain way. We hope to begin putting signage up this week, at the entrances to the reserve and also at path junctions, so if and when you do visit please keep an eye out for them. Hopefully we will have ironed out any snags by the time we are able to open a car park, which fingers crossed will not be too far off now, we will keep you all posted…

It has been nice to spend a bit of time out on the reserve – I was back just in time to experience the bluebells along the Dockens Water, although they are going over now, and also heard my first cuckoo of the year this week. I wasn’t sure I was going to hear one this spring. There is also still some greater stitchwort flowering along the Dockens path:

On Ibsley Water the large raft is mainly occupied by black-headed gulls, although there were a couple of common tern on there early last week. It’s lovely to see the common terns back again for another summer.

By the Centre there has been plenty of insect life around the pond, with beetles, bees, dragonflies and damselflies making the most of the sunshine:

On Wednesday Bob and I were sat having lunch when the female mallard he had noticed on the new Education Centre pond made an appearance, followed by 13 ducklings. We watched them topple off the boardwalk into the water, one or two at a time, and enjoyed their company whilst we finished eating. Later on that afternoon they moved over to the original centre pond but I haven’t seen them since, so I hope they are ok.

It has also been really nice to be able to rummage through the moth trap again, although with a few cold nights it has been quite quiet. Here are some moth highlights:

There have also been a number of cockchafers in the light trap. Also known as May bugs or doodlebugs these large brown beetles also fly around at dusk.

On Thursday I found the exuvia or final moult of a hawker dragonfly in the pond and fished it out to take a closer look:

Leaving it out in a sunny spot to dry out I completely forgot about it, only remembering once I had driven home that evening. By this morning though it had found its way onto my desk, so Bob must have spotted it too!

I have also visited the meadow a couple times, the oxeye daisies are looking beautiful now they are coming into flower, rivalling the gorgeous pink display of ragged robin by the Welcome Hut which Jo shared a photo of last week. The common vetch and buttercups are also flowering and there are a few common blue butterflies on the wing.

The beautiful green beetle above has many names, it is known as the thick-legged flower beetle, false oil beetle and swollen-thighed beetle. Only the males have thickened hind legs, I might have to visit the meadow again in search of a female.

Row, row, row your boat

As yesterday was so gloriously sunny, our Young Naturalists enjoyed a day exploring the further reaches of the reserve and finishing off a fun task started back in January at our volunteer get together.

We began the day though with our usual rummage through the light trap, where the group were thrilled with a good selection to identify, their best so far this year. Our haul included the following: white ermine, cinnabar, treble lines, poplar hawkmoth, common marbled carpet, marbled brown, orange footman, common white wave, angle shades, light brocade, brown silver lines, common pug and marbled minor. Here are a few photographs taken by Young Naturalist Talia Felstead:

It was then time to undertake a practical task with a difference, the lining of the coracle made earlier in the year at our volunteer get together. Coracles are small oval shaped boats traditionally used in Wales, but also in parts of western and south western England, Ireland and Scotland. Designed for use in swiftly flowing streams they have been in use for centuries, primarily by fishermen.

The structure is usually made up of a framework of split and interwoven willow rods, a material which we have plenty of here on the reserve, so it seemed silly not to take the plunge (literally) and attempt our own Blashford coracle.

The group were up for the challenge of finishing it off, cutting a slightly less traditional liner out of some left over pond liner from Testwood Lakes – thank you Testwood! This outer layer would have originally been an animal skin, covered with a thin layer of tar to make it fully waterproof. Today this has been replaced with tarred calico or canvas, with the Blashford way being whatever we could lay our hands on. So pond liner it was!

We carefully cut the liner to size, before Bella came up with the idea of looping cord through slits cut in the liner and weaving it in and out of the liner and willow rods. It was then time to take it down to the river for the all important will it float test…funnily enough no one else was brave or silly enough to give it a go:

Excitingly, it floats rather well, I think to the disbelief of some of the Young Naturalists, and possibly volunteers! So now we can get cracking with the rest of the flotilla…with plans already in place for a coracle themed Wild Day Out for the older children in the summer holidays.

After lunch we headed over to the northern side of the reserve on a wildlife hunt. We quickly spotted large numbers of Common blue damselflies sunning themselves on the gravel, moving a little further ahead as we approached them:

We headed up to Lapwing hide where on entering we were greeted with this view of a Canada goose with seven goslings:

We stayed for a while, spotting a couple of herons, a little grebe and watching a Common tern fishing over Ibsley Water before perching on one of the posts:

On our way back, Edie somehow spotted this Elephant hawkmoth in the long grass to the right of the path:

Finally, our last wildlife spot was this Beautiful demoiselle, which perched beautifully for a photo:

As all the serious players on the Trust payroll were at a staff meeting today, it was left to your’s truly to manage the reserve today.  Not a problem, but it’s a bit unusual for me to be here midweek.

A quiet sort of day with enough heat to keep a few insects active including good numbers of damselflies, mostly large red damselfly and azure damselfly, but all were a little too skittish for me to photograph.

Our recent resurrection of the light trap is starting to pay dividends as there was a range of interesting species last night so I’ll share a few pictures with you.

First a couple of moths whose markings are an intricate pattern of browns and cream colours, perhaps, somewhat understated…
