Etorofus obliteratus

This is a common Longhorn Beetle (Cerambycidae) of coniferous forests in our region. They range in size from 9mm (male) to 17mm (female). The head is black. The pronotum is black, with flattened hairs pointing backwards, and flares posteriorly to cover the shoulders of the elytra. The elytra are tapered, about 2 1/2 times as long as wide, brownish yellow with black medial and apical bands, and do not cover the abdomen. Sometimes there is a dark oval area between the shoulders and the medial band. 

The larvae feed on the decaying wood of various conifers. Adults feed at a wide variety of flowers. This specimen was found on Daucus carota (Queen Anne’s Lace). They are found region wide in coniferous forests, and the adults are active from May to September.
