Family: Cerambycidae

Subfamily: Cerambycinae

Length: 7-10 mm

 

Look for these odd longhorned beetles resting on the bark of tree trunks in mid-April to early May. Their size, coloration, and the shape of their heads will lead one to think that they are ants, at first. Upon closer examination, those very long antennae make it seem more like the Longhorn Beetle it is. Looking closer still, notice that the white markings are actually formed by white pubescence, and the gray-tan area at the rear of the elytra is very densely pubescent.

The larvae are at home on dead but not decayed hardwood trees. Adults may be found not only on tree trunks, but on flowers too, and are also attracted to lights.
