Madagascar Hissing Cockroach
Madagascar Hissing Cockroach Scientific Name: Gromphadorhina portentosa
Madagascar Hissing Cockroach Facts
These huge insects push air out of a pair of breathing holes, called spiracles, on the sides of their bodies to make their distinctive hissing noise. They are the only insects that make a hissing sound this way. There are three types of hisses—disturbance hiss, female-attraction hiss, and fighting hiss. The disturbance hiss is the one most people hear. Older nymphs and adults, both male and female will make a hissing noise when handled or disturbed. Females and nymphs only make the disturbance hiss.
Madagascar Hissing cockroaches are one of the largest types of cockroaches in the world. In their natural habitat on the island of Madagascar near Africa, Madagascar Hissing cockroaches like to live in rotting logs. Male Madagascar Hissing cockroaches tell the difference between known males and strangers by the hissing sound they make. Males are more aggressive than females. Males are territorial and fight amongst themselves, ramming and pushing each other with their abdomens and horns. Hissing can be used to relay information about the size of the cockroach making the noise. At the end of the fight, the winner will make a loud hissing sound to declare his victory. Bigger males usually win out against smaller males. Although Madagascar Hissing cockroaches are usually active at night, males can be seen fighting during the day.
Males also hiss when courting females. They mate end to end with the male pushing his abdomen along and under the female’s body until he reaches her abdomen’s end and engages with her.
