Pristiphora confusa - Confounding Sawyer
Pristiphora ruficornis

Males are best determined by examination of the penis valve. Females are difficult to separate from Pristiphora armata, leucopus, opaca and subopaca requiring detailed examination of the saw. The apical serrulae are more protruding, but shorter, than in Pristiphora opaca and Pristiphora subopaca.

Pristiphora confusa larvae feed on goat willow, crack willow and tea-leaved willow.
