Scientific Name: Blatta orientalis
Description: When mature, male Oriental cockroaches are red-brown to black and about 1” long. Females are 1 1/4” long and the same color as the males. In males, the wings cover 75% of the abdomen whereas with females they are reduced to small wing pads. Nymphs are light brown but increasingly become darker with each developmental stage or molt. The purse-shaped egg capsule (ootheca) is dark red-brown but becomes black with age, 3/8” long, and typical gas 16 eggs enclosed.
