The name uropygid means "tail rump", referring to the whip-like flagellum on the end of the pygidium, a small plate made up of the last three segments of the abdominal exoskeleton.

Whip scorpions have glands near the rear of their abdomen that can spray a combination of formic and acetic acid when they are bothered.

The acetic acid gives this spray a vinegar-like smell, resulting in the common name vinegaroon.
