Origin:
Not mentioned, but it is a tropical species currently found in Africa, Europe, Asia, Australia and the United States, where it is a resident in Hawaii and Florida, and it occurs in other southern states. It also has been found in California as a possible import from Asia in food packaging.
Biology:
The name “lobster” is derived from a lobster-like design on the prothorax. It is an outdoor dwelling species that has even been found as a predator on other cockroaches in Hawaii. It may be transported in commodities such as grain, fruit, or vegetables.
Identification:
Adults are about 1.3 inches long and are ashy gray in color. The males and females are both winged, with the wings shorter than the abdomen.
Characteristicts Important to Control:
These are uncommon insects in the U.S. and should be treated in a manner similar to American roaches when found. Reduction of food and moisture sources, reduction of harborage, and crack and crevice treatment with a residual insecticide are effective.
