Madagascar Hissing Cockroach

Gromphadorhina portentosa

Invertebrate | Sub-Saharan Africa and Madagascar

Animal Info

Unlike most cockroaches, Madagascar hissing cockroaches do not have wings; however, similar to their cousins in the wild, they do have six legs. They get their name for the four hissing patterns that they display: a male aggression hiss, two courting/mating hisses, and an alarm hiss to ward off predators. They also can communicate through pheromones. Pretty neat for a bug!


In the wild: Carrion, plants, and other bugs

At the Zoo: New world primate biscuits
