A true bug, not a generic sort. Damned if I can find out what it is though. The lovely gallery over at British Bugs is a nice browse but I've missed it if it's there - not surprising if you ever saw me trying to find stuff at the supermarket. I have put out a general alert to the super-mind that is the PSL* facebook page. Fingers crossed.

Wow - about five minutes. That's how long it took, and as expected it really was on british bugs at here
More micro pics showing other features, e.g. black pronotum, orange legs
