Similar to Colorado Potato Beetle (1), but elytral punctures are regular instead of irregular. Also, a brown stripe at the center of each elytron (wing cover) and on the inner edge of each elytron (where they meet down the middle) distinguish this species.

Larvae are hump-backed and have one row of black spots down each side.
