Sawfly - Heterarthrus nemoratus

Sawfly - Heterarthrus nemoratus
Seattle, King County, Washington, USA

Size: 5mm
I chased this sawfly through my birch leaves. I've been trying to catch one of these little sawflies for a year, now. I certainly can be wrong about the identification, but right now, I'm pretty confident. This particular tree is usually covered in leaves mined by this sawfly. I didn't see it oviposit, so I don't know if it's male or female. This is the time of year that I would expect to see the adults, though.

Moved tentatively per Dr Smith's comment
