Pristiphora staudingeri (Ruthe, 1859)

Pristiphora staudingeri - ruficornis group

This species inhabits arctic and subarctic regions and is similar to Pristiphora luteipes and the two cannot always be distinguished by morphology. Males are best determined by examination of the penis valves. Determination of the females, is best done by examination of the saw.

Pristiphora staudingeri larvae feed on dwarf willow and tea-leaved willow which are both upland species.
