American Cockroach Mating
American cockroaches engage in courtship rituals before mating. Females begin courtship by raising their wings, exposing their integral membranes, expanding their genital chambers and releasing a pheromone that attracts males. This stance is referred to as the calling position.
Attracted males approach females and flap their wings to denote interest. Reproduction commences when a male cockroach backs into a female cockroach, depositing sperm.
After fertilization, a female American cockroach produces an egg case known as an ootheca. The female carries the ootheca on her abdomen for a short time, usually a day or two. After that, she deposits it in a warm humid location.
