Here ya go, bendyfoot--I have some others, but they're all pretty much the same. Dad-burn things wouldn't uncoil.
I did see one unfurled and it was maybe an inch-and-a-quarter or an inch-and-a-half long... When they're curled like that the circle is about an inch in diameter. The eye interpreted the dark as black but the camera seems to have seen a very dark blue.
There are three of them hanging out on the same plant in the middle of what's basically a grassy field.
Notice the double dorsal stripe...and that smooth-domed, Einstein brow! Must be a real genius with that egg-head, eh?
