Labia minor is about half the size of Forficula auricularia,[2] at 4–7 millimetres (0.2–0.3 in) long.[3] It is chocolate brown, and less shiny than the chestnut brown F. auricularia.[4] The whole body is covered with fine yellow setae, and the antennae are a paler color.[5] The forceps (pincer) at the animal's tail are used to help unfurl the wings, in preparation for flight.[3] Unlike F. auricularia, Labia minor flies frequently.
