Moved from "Symphyta" - Sawflies, Horntails, and Wood Wasps.

This seems to be a dead ringer for the species, though its known introduction is in a couple eastern states / provinces (ON & NY). Definitely double-check that the location is accurate.

From the first published report in the Americas: "Diagnosis.—In North America, the mostly bright orange color (Figs. 1, 2), annulated tarsomeres, and slightly clubbed antenna (Fig. 3) of the adult and the mostly blue-green larvae should make this species easy to notice in the field."

While there are other orange-bodied species and other species with a strong black margin to the wing that could possibly cause confusion (Monostegia abdominalis is mentioned in the paper, and there are certain Nematinae), all of the alternatives that I see lack the black rings on the tarsi and apex of the tibiae. They also differ in the structure of the antennae.

Spencer has noted another suspect individual here outside of the original published area.

Moved from ID Request.

Your August submission looks even more like Tenthredinidae. I don't think these are Rose Sawflies--but I'll leave them here for now in the hope that a specialist will eventually have a look at them.

It does superficially resemble A. ochropus, but the antennae look more like those of a Tenthredinid. Also, BG has no records of A.. ochropus from anywhere near Oregon. Do you have any other shots?
