Sawfly - Trichiosoma triangulum - Male
5 mi. south of Port Angeles, ~2,000 ft. elevation, Clallam County, Washington, USA
December 31, 1969
Size: 2.5 cm
At least three sawflies of this species were circling around, interacting in flight and occasionally landing on vegetation. They landed over and over. This is Western Yew, Taxus brevifolia.

This individual could be identified among many photos because of the Y branches on certain veins on the right wing.
