Macrophya rufipes - Dewberry Strider

Recorded widely in England and Wales south of the Humber-Mersey line (Musgrove, 2023).

In the male the abdomen is usually red banded across three tergites and two in the female. However, the red bands may be absent. In the female, the abdomen has white lateral marks on at least tergites 1 and 6 and a dorsal white mark on the apical tergite. The hind femora are red almost from the apex to the base in both sexes.

According to Macek, the larval foodplant is dewberry in shrubby grassland and the larvae are about from mid-June to September.
