I noticed this insect while pumping gas at a gas station near Ritzville, WA. It’s legs will twitch spontaneously like a yellow jackets’ back legs do. It stayed very still otherwise.

This Locust Borer is a very effective Yellow Jacket Mimic. Adult Locust Borers are often found on goldenrod in the autumn. Larvae bore into black locust trees. According to BugGuide: “Considered a serious pest of Black Locust trees; previously weakened or damaged trees are often killed by an infestation of the larvae. Previously confined to the native range of Black Locust in the northeast, it has spread with the trees throughout the US. Unfortunately Black Locust is used for reclamation and similar projects where trees are likely to be stressed out and thus more vulnerable to insect damage.”
