So I quickly got changed, got me boots on and strode off down the lane. I had nothing with me other than camera and a few pots, and all I was intending to do was roll a few stones etc looking for carabids. I eventually got over to a small wooded copse at the back of the fields that is completely wild and unloved. I did get permission to go in there from the farmer a few years ago, though I'm sure he'd have forgotten by now. When I used to go down there, there was a bit of a track and the wood was quite open but with a dense canopy - mainly young ash and birch. That was a few years so, today it seems like most of the trees have blown or fallen over, with broken branches and trunks all over the place and almost more deadwood than live. Access not easy either. Still, I had a quick poke around the rotting logs and soon potted up a few Pterostichus spp. and others to work through.
The first one I checked through was Pterostichus madidus - predictably. Up until now I've never retained specimens in any structured way, as I prefer a photographic record, but it's something that I know I need to do eventually if I'm ever going to focus on coleoptera properly. So, I had a go my first carding attempt. A bit of a cack handed effort, slightly wonky on the hastily cut bit of card, but I'll work on it. I need to sort out how to minimise the glue and work out how to better arrange the legs and bits. This one is carded, but has a gobful of PVA and in reality it's not possible to re-work it through the key.
Slightly weird striae on left elytron
Fine setae on dorsal surface of hind tarsi
I'll print labels tomorrow and add to the pinned cards in the storebox.
I'll key the others out, and I also found another Drymus-type ground bug to check.
Whilst in the dark deadwood, I noted a couple of fungi too ...
Common Eyelash sl
Lemon Disco sl
I'll have to have another poke around there sometime when there is a bit more light and warmth.

I'll admit, an eyebrow shot up (quite involuntarily) when I saw the carded Pterostichus, now you're a 'real' entomologist! I stubbornly refused to card for years, pinning being the preferred method. But I card everything now. I'm still shite at it, but occasionally I manage one that's passably straight and symmetrical. Good work, buddy!
I'll keep practising Seth, I'm hopeful of another couple of decades at least to get somewhere near proficient! Before then I fully expect to glue a Bembedion to my elbow.
Best place for them - not exactly my favourite genus!
