The Madagascar hissing cockroach, Gromphadorhina portentosa, is known for its distinct hissing sound produced by expelling air through its spiracles. These large, wingless roaches are native to Madagascar's forests, thriving in warm, humid environments. They play a crucial role in the ecosystem by decomposing organic matter.

Gromphadorhina portentosa, commonly known as the Madagascar hissing cockroach, is native to the island of Madagascar, located off the southeastern coast of Africa.

This species typically inhabits the warm, humid environments of Madagascar's tropical forests. The climate in these regions is characterized by high humidity and temperatures that generally range from 20°C to 30°C (68°F to 86°F).

The Madagascar hissing cockroach is primarily a forest floor dweller. It thrives in decaying organic matter, such as leaf litter and rotting logs, where it plays a vital role in the ecosystem as a decomposer. By breaking down organic materials, it contributes to nutrient cycling and soil health. This species is also known for its unique ability to produce a hissing sound, which is used for communication and defense.
