Smokybrown Cockroach Life Cycle

Habitat

The smokybrown cockroach requires a year or more to complete its life cycle from egg stage to adult stage. However, since these cockroaches are frequently found outdoors where temperatures vary greatly by location and time of the year, the timeframes to complete their life cycle will vary greatly. In some areas, these cockroaches are reported to take a few years to complete one life cycle.

Life Cycle of Smokybrown Cockroach

Smokybrown cockroaches go through three different life stages – eggs, nymphs and adults. Nymphs are similar to adults in appearance except they are smaller, have a whitish colored band on their thorax and do not have wings. Adults are about one inch long, have well-developed wings that extend beyond the tip of their abdomen and are blackish-brown in color.

The females carry an egg case that contains around 20-26 eggs, which take about 50-80 days to incubate. Once the eggs in the case hatch, nymphs go through several stages over a period of about 9-10 months prior to becoming mature adults. As adults, they will live for about 2-6 months, but in some environments adults are reported to live much longer.
