Pristiphora staudingeri - Staudinger's Sawyer
Pristiphora ruficornis group

Small numbers of records from the mountains of Scotland, Cumbria and North Wales. Two records from the southern Pennines require further investigation; one of the foodplants (Salix phylicifolia) does occur very locally in the latter area but the records were not specifically noted as being in close proximity to this plant (Musgrove, 2024).

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.
