This is the time of year when we get incorrect reports that locust borers (M. robiniae) are emerging from firewood in and around homes. This is another longhorned beetle that is closely related to the painted hickory borer and both beetles share similar markings. It is common for homeowners who are relying on online identification resources to make an incorrect ID. However, painted hickory borers emerge in the spring and locust borers emerge in late summer to early fall at about the same time common goldenrod (Solidago canadensis) is in full bloom. In fact, locust borer adults are most easily spotted on goldenrod partaking of the pollen and nectar.
