Calameuta pallipes - Pale-legged Stem-sawfly

Perhaps the most widely distributed cephid in Britain, with records as far north as the Moray Firth (Musgrove, 2022). The smaller of the two Calameuta species present in Britain and Ireland. Calameuta pallipes has the hind tibia predominantly yellow, whereas filiformis has black tibia. The males have broad yellow apical bands on the tergites. However, females have an entirely black abdomen.

Larvae feed inside the stems of plants but it is not known which species.
