The Banded Longhorn is a slender, wasp-mimicking longhorn beetle with alternating yellow and black bands on its elytra and a striking resemblance to a yellowjacket wasp. It is frequently found nectaring on flowers, especially milkweed and goldenrod, reinforcing its mimetic disguise. Larvae develop in roots and decaying wood of deciduous trees.
