 Madagascar Hissing Cockroaches Their scientific name is Gromphadorhina portentosa They live mainly in Madagascar Males have large horns which they use to ram other males Their hissing sound is part of their mating ritual and also serves as an effective warning call They make their sound from exhaling through breathing holes instead of using vibrating membranes like most insects Contrary to common belief, Madagascar Hissing Cockroaches are not pests and don't live in dwellings where people live. They actually live on the forest floor! Cockroaches are somewhat active during the day, but are the most active during the night.
