Paul sends in this shot of a mystery beastie, photographed in a small cave in the north east of England. He describes it as follows. "At first glance it looks like a cricket but lacks the hind legs etc. Its antennae bend backwards and it has two long appendages from the rear."

I can't figure out what it is, having searched the interwebs long and hard. Some sort of bristletail, or a larva of some sort? What's most annoying is that I swear I've seen such a thing before, but I can't bring it to mind. I bet there's someone out there who knows exactly what it is at a glance. Please tell us!
