A large number of these was beneath a soggy clump of mowed grass that had been thrown up on a log. They instantly began to scurry in all directions as I lifted the clump. I did the licked-finger dab and picked one up to bring back to shoot at home. This is probably as much detail as I can muster with the built-in flash alone, though I might still be able to increase ambient lighting (but at the risk of frying my subjects).
