Forficula uriculari (Forficula auricularia)
Adult: The adult normally measures 13-14 mm in length, exclusive of the pincher-like cerci (forceps), though some individuals are markedly smaller. The head measures about 2.2 mm in width. Adults, including the legs, are dark brown or reddish brown in color, though paler ventrally. The antennae have 14 segments. Despite the appearance of being wingless, adults bear long hind wings folded beneath the abbreviated forewings. Although rarely observed to fly, when ready to take flight the adults usually climb and take off from an elevated object. The hind wings are opened and closed quickly, so it is difficult to observe the wings.
