Pristiphora subbifida - Subdivided Sawyer
Pristiphora depressa group

North to Yorkshire and relatively frequent in recent years, perhaps increasing as Benson (1958) considered it to be scarce (Musgrove, 2024).

Males are unknown. The head is yellow with a large black patch encompassing the ocelli and on the thorax the metapostnotum is at least partially pale. The female is best determined by the characteristics of the saw and sawsheath.

Pristiphora subbifida larvae feed singly on field maple eating from the leaf edge.
