Description |
||
Minnesota longhorn beetle is a moderate-sized flower longhorn beetle, ½″ to ¾″ in length. Males may have longer antennae but are otherwise indistinguishable from females. The thoracic plate (pronotum) is narrower than the base of the hardened wing covers (elytra), and is densely covered with straight tan hairs. The elytra taper evenly from the base to the blunt tip. They are mostly bronze-colored but black at the tip. The compound eyes are large, bulbous, and oval. They do not wrap around the antennae bases. The face slants forward. |
