Thanks for the replies. I've just been sitting there trying to look in every little hole in every piece of rock while I was waiting for replies

.
After reading you response about the Hermits Davek maybe it makes abit more sense now. The half of the hermit I found was the front half. I could probably scan it (havent got a camera) if you wanted to see it.
I'll have to wait and see what happens I suppose. If I notice my hermit numbers dwinderling then something is probably wrong. Got a 4 different types of snail coming Friday and was starting to think about there lives too incase it was a mantis.
Thanks for the replys and i'll keep informed on any future happenings.
Thanks
