Mad caterpillar

Was taken some macro blips of flowers, and this caterpillar was on a giant leave - it was giant as well. The size of my hand, actually. I moved the leave to hold it still unfortunately it fell on the floor. I moved it with a piece of paper ; O lord it was not happy I tell ya... For the world of me I can not look beside its head looking like its in 3-D with an eye in it, it looks indented. Weird looking creature. Better looked @ enlarged.
