Endophytus anemones - Wood Anemone Sawfly

Scattered records in England and Wales. Since its initial discovery (Benson 1961a), it has remained unaccountably rare, given that the foodplant is widespread and there has been an increasing interest in the recording of leaf-mines. It still seems likely that it is hugely overlooked (Musgrove, 2024).

Males are unknown. Females have at least the base of the hind femora completely black on at least one face. Entirely black body with pale labrum, clypeus in part, tibiae, tarsi in part and the apices of the femora. The wing venation in this species is unstable and anomolies are common. See LIston et al, 2019.

Endophytus anemones larvae mine the leaves of wood anemones and naturalised wood ginger.
