At the end of the abdomen, the male has a pair of styli, while the female has a pair of valves separated by a transverse groove. Glands on the body of insects secrete a smelling secret that attracts insects to each other. Therefore, black cockroaches live in large groups.
Habitat and lifestyle
This type of cockroach is found throughout Europe, Asia and Africa. He lives in wildlife and in human dwellings, in greenhouses, basements, sewer manholes. The black cockroach is omnivorous and feeds on garbage. Although he has wings, he does not fly, but he runs very fast.

Small black larvae or nymphs emerge from the eggs and quickly scatter in different directions. They can live without food and water for two months. From the appearance of an egg to an adult in favorable conditions, 5-12 months pass, during which time the larvae have up to 10 molts. At low temperatures and lack of nutrition, the period of growing up can stretch up to 5 years.
