The elm borer is a longhorned beetle whose larvae bore galleries under the bark of elm trees. It is one of the insects that can transmit the fungus that causes Dutch elm disease, but it is not the fungus's main vector. The elm borer is in a large subfamily called the "flat-faced longhorns."
Adults are seen from May to August. The orangish markings on the adults are distinctive, as is the fine coating of grayish hairs on most of the body.
