Very cool find from last spring- a Florida vinegaroon (Mastigoproctus floridanus) that was hiding inside a rotting log.
despite her impressive size, this rarely encountered Florida endemic is actually the smallest of the 3 vinegaroons in the US, and some of the Mastigoproctus species from Mexico and southwards get even larger.
and yes they’re called vinegaroons (among other fun names) because they squirt concentrated vinegar from their butt as a chemical defense
