30 Days Wild – Day 22: Punctuated

It was thankfully cooler today which allowed us to do some work along the open western shore of Ibsley Water. As it was Thursday the “us” was the famous Blashford volunteer team. We were trimming brambles and pulling ragwort. I know ragwort is a great nectar source, but in this case we are trying to establish grassland where there has been bramble, willow and nettlebeds, this means mowing, but as we have ponies on site we need to remove the ragwort first. Ponies will rarely eat growing ragwort, but if cut and mixed in grass they will and so can get poisoned.

This shore was dominated by huge beds of ragwort and nettles but years of cutting and light grazing are taking effect and we now have mostly grassland with patches of ox-eye daisy, bird’s foot trefoil and other more desirable species. In turn this is attracting insects such as long-winged conehead.

We saw a good few butterflies including good numbers of comma. It seems they are having a very good year and the fresh summer brood emerging now is particularly strong. This generation will breed and produce another generation of adult in the autumn which will them hibernate.

They get their name from the white comma-shaped marking on the under-wing, which is not visible in this shot. Their ragged wing outline makes them less butterfly-shaped and so harder for predators to find, this is especially so when the wings are closed.

I ran two moth traps last night, only about 50m apart, but one under trees and the other in the open. An illustration of what a difference location makes is seen from the number of hawk-moths caught. The one in the open contained 8 elephant hawk-moth, a pine hawk-moth and 2 poplar hawk-moth, whereas the one under the trees contained just one eyed hawk-moth.

As you will have gathered from this blog, I am a fan of insects in general, even horseflies, although I am less keen on them when they come into the office as this one did today.

It is the females that bite, so it would be better if this one went outside again.

Hawks and Colour Rings

By the standards of this summer today was a good day, it hardly rained and certainly not enough tot prevent working outside all day. The night was also dry and this resulted in a fair catch of moths including a couple of hawk-moths.

They are both common species but always a treat to see.

There were also lots of less flashy species, including a bloodvein.

And  a few are downright tiny.

Caleophora albitarsella

This is one of the most distinctive of a large group of very small moths that make a leaf case to live in as caterpillars, they then move around rather like a snail. The shape of the leaf case is often the easiest way to identify the species as the adult moths look very similar to one another.

We spent the morning path cutting on the far side of Ellingham Lake, I say “we” as I have the assistance of a school student on placement. The chance to get outdoor work done without getting soaked was too good to miss so in the afternoon we weeded a section of the shore in front of the Tern hide to improve the view and see off some of the perennial weeds and small trees that have seeded in there. It was even warm enough for us to see a few butterflies and other insects including this pair of beetles, sometimes known as blood-suckers.

Rhagonycha fulva

The count of mute swan on Ivy Lake continues to rise and I counted at least 42 this evening. On Iblsey Water from the Tern hide as I locked up I saw 2 common sandpiper, a dunlin in very fine summer plumage and a colour-ringed cormorant, I have yet to establish exactly which scheme it is from, but I think it is one from France, hopefully more to follow on this. The combination seems to be blue above white on the right leg and orange over green on the left.
