Gourt Home::Gourt :: Madagascar hissing cockroach
The Madagascar hissing cockroach (Gromphadorhina portentosa) is one of the largest species of cockroach, reaching 2-3 inches at maturity. They are originally from the island of Madagascar off the African coast. Also, they are wingless, an uncommon attribute in the cockroaches of the world; however, they are excellent climbers and can easily climb smooth glass.
Hissing
It is a very popular pet because of its hissing sound, large size and interesting appearance. Their namesake "hissing cockroach" is due to their ability to force air through the breathing pores (spiracles) found on their abdomen. The Madagascar Hissing Cockroach is believed to be the only insect that can hiss in this manner, as most insects make a "hissing" sound by rubbing together various body parts. This hiss is used in two contexts: the disturbance hiss and the fighting hiss. All cockroaches from the fourth instar (fourth molting cycle) and older are capable of the disturbance hiss. Only males use the fighting hiss when challenged by other males.
Popular culture
It has become a popular insect in Hollywood movies, featured prominently in Bug (1975) (as 'roaches who could set fires by rubbing their legs together), and in Damnation Alley (1977) (as post-nuclear-war mutant armour-plated "killer" cockroaches).
