Macrophya albipuncta - Crane's-bill Strider, Crane's-bill Sawfly

Benson (1952) only knew this species from Yorkshire northwards, but it has subsequently been found in southern England also. However, it appears to be generally uncommon and absent to date from Wales, southwest England and East Anglia (Musgrove, 2023).

One of the smaller, predominantly black, Macrophya species. This species has white marks on the sides of the apical margins of the tergites and the sternites. The stigma is pale-centred but with dark margins. The head is shining with sparse punctures. The eyes are green in life.

Macrophya albipuncta larvae are free feeding on crane's-bills.
