Insect activity is probably as low as it gets around this time of year, but there is always an arachnid or two around if you look hard enough! One of the groups you are most likely to see are the spiders of the genus Pardosa, in the Lycosidae family (often known as Wolf spiders). They are easy to recognise to genus level by their appearance; generally medium sized with obviously hairy stout banded legs and a very distinctive eye pattern. They are found running rapidly across almost any low level warm surface that gets plenty of sun, and the females may carry a silk egg sac with them. A binocular microscope is needed to determine Pardosa to species level though.
Even a brief spell of sunshine provided it is enough to warm the open ground they prefer will often bring out significant numbers of these spiders; the temperature is 7 degrees outside and I have just counted more than twenty Pardosa spiders basking in the sun on a 2 metre stretch of gravel.
I've also been using the winter evenings to go through some specimens that I collected last summer. One of them was Pardosa hortensis:

Pardosa hortensis - sorry about the photo! |
It is an uncommon find for Wales, and indeed looks like it is one of a handful of records this side of the border though I have a recollection that there may be a couple of sites in the west of VC41 where it has been recorded.

And if Nigel happens to be reading this, there was another Bombus terrestris in the garden today. It looks as though they are successfully over-wintering here. This time it was feeding on a Grevillea which is blooming right now.
