Northern Rough Greensnake
Opheodrys aestivus aestivus
These pretty little snakes seem to disappear when they slither into the grass, they are very well camouflaged. They are non-venomous, so they are not dangerous to handle. However, they have a quite effective method of repelling potential predators (and science teachers, as I found out!) --- they wrap their tail around whatever is holding them and smear foul-smelling poop! Yucch!
