The Australian Cockroach
The nymph (or immature) is at the upper left, and the adult is on
the lower right. Many roach species have strong mandibles that are capable of
producing postmortem damage to human skin that resembles abrasions or chemical burns.
In many cases these abrasions appear as small pits in the skin. Additionally,
roaches often consume human hair, and may frequently remove entire hair shafts during
their feeding. The roach species most commonly encountered in forensic
investigations are the American, Australian, and the German.
