| Size: | Oriental cockroach adult males are about 1 in (25 mm) long; females are about 1 1/4 in (32 mm) long. |
| Color: | Usually shiny black, but varies somewhat, and can go to a dark reddish brown. |
| Characteristics: | Males' wings cover 75% of abdomen, females' wings are much smaller. |
| Geographic Range: | In spite of common name, probably from north Africa; also known as a "shad roach", "black beetle", or "water bug"; found around the world. |
| Food: | Oriental cockroaches feed on all kinds of food, especially starchy ones. They also eat organic matter that is in the process of decaying. |
| Biology: | Female usually deposits her egg capsule within about a day (up to 5) after its formation. It may be dropped onto or glued to a surface that is warm and protected, and near a source of food. She will produce on average about 8 egg capsules (16 eggs each) during her life. Development from egg to adult varies depending on temperature; at room temperature it takes about 20 months. Adults live from about 1 to 6 months. |
