This little guy was writhing about on top of some moss in my garden. It would lift its head, waving, mouth half open, like a dog trying to follow a smell.
Never seen a worm snake act like that. It didn't appear to have anything wrong with it. I watched it writhing for about a half hour before I left it. An hour later it had vanished.
This little guy emerged to shed his skin!
I thought it was a worm, until I saw a tongue. :)
Observed 5/22/16 while turning compost (and the compost started wriggling). It had a pink underside and tied itself in knots while being handled.
