Pristiphora punctifrons - Stippled Rose Sawyer
Species not placed in a group

North to southern Scotland, seemingly common and widespread (Musgrove, 2024).

Females can be distinguished by the very deep scopa of the sawsheath, mostly black dorsum and tarsal claws with a tiny subapical tooth. Males are rare and are best determined by examination of the penis valves.

Pristiphora punctifrons larvae feed solitarily on dog rose and cinnamon rose.
