American Cockroach
Physical Features
Adult males and females are 1 to 2 inches long, reddish-brown to dark brown except for a light yellow band around the shield behind the head. American cockroaches have a flattened, oval shape, six spiny legs and long antennae. Immatures/Nymphs are shorter than adults with undeveloped wings, but otherwise similar to adult forms. Females’ wings are same length as the body with a broader abdomen than the males. Females produce egg cases (oothecae) that extend from their abdomen before they are dropped. Males’ wings extend past the length of their abdomen. They have cerci extending from their abdomen, which are short antennae serving as back up feelers.
Life Cycle
Gradual metamorphosis
Reproduce at a slower rate in comparison to other cockroach species. Females deposit egg cases (oothecae) in hidden areas or will glue them to the side of a structure. Up to 16 immature cockroaches (nymphs) will emerge from the case in 5 to 7 weeks. Nymphs will molt 10 or more times in a year before becoming an adult. Adult cockroaches can live up to one year producing an average of 150 young during that time.
