One of the most unique features of the earwigs is the “cerci” or pincher-like appendages that come off of their hind end. The females have curved cerci and the males have straight cerci. Adults grow to between ¼ and 1 inch in length, their brown legs are lighter in color than their reddish brown body.

Other distinguishing features include a pair of very long thread-like antenna that is almost half of their body length and their four wings- two short front wings, and two long hind wings.
