These cockroaches are shiny brown and oval-shaped, with no wings and a single pair of antennae. Males sport large horns, which give them an unusual and impressive appearance.
They are from the island of Madagascar off the African coast, where they can be found in rotting logs, leaf litter, and other detritus.
At night, they become more active and scavenge for meals, feeding primarily on fruit or plant materials. At the Zoo they are fed apples and other fruit.
The Madagascar cockroach has become characterized by its hissing sound, large size, and appearance. In this insect, sound is produced by forcibly expelling air through a pair of modified abdominal spiracles. Spiracles are breathing pores which are part of the respiratory system of insects. Because the spiracles are involved in respiration, this method of sound production is more typical of the respiratory sound made by the vertebrates.
They are common and not endangered.
The Madagascar Hissing Cockroach can be found at the Insect Zoo.
