Bodies are ovate to oblong, ranging in size between 0.4 and 1.4 inches long, and they are jet black or occasionally dark brown. They may be smooth or rough, and elongate or robust. The head is prominent and slightly narrowed behind the eyes. A few varieties have hair-like structures and what looks like a tail, but is actually elongated wings. Like all insects, they have six legs. Thickened, leathery wing-covers protect the delicate flight wings, which they do not use.
