What is a key identifier regarding the wing structure of Rove Beetles?

Answer

Their elytra are unusually short, leaving abdominal segments exposed.

One of the most recognizable physical characteristics distinguishing Rove beetles from many other beetle types is their specialized wing structure. Although they are classified as true beetles, their elytra, which serve as the hardened protective covers for the wings, are notably short. This shortness results in several abdominal segments being left uncovered and visible when the beetle is at rest. This feature contributes to their distinctive, somewhat streamlined appearance compared to beetles whose elytra meet neatly over the entire length of the abdomen.
