A male bedbug (Cimex lectularius) traumatically inseminates a female bedbug. The female's ventral carapace is visibly cracked around the point of insemination. Bedbugs reproduce solely by this process, in which the male pierces the female's abdomen with his penis and injects his sperm through the wound.Photo: Rickard Ignell, SLU
