Paper wasp on top of her nest. Hate to do it, but I'll probably have to removed her nest from my son's treehouse. I've heard that a paper wasp is just about one of the most painful of all insect bites.
Real nice picture with good focus and sufficient DOF. The backlit jaws look really dangerous! and he almost crouches in order to jump you! Horror movie-stuff! Thanks for sharing! Ciao, Ragnar
