Madagascar Hissing Cockroaches

GROMPHADORHINA PORTENTOSA

These cockroaches grow to be 2-3 inches long.

Can live up to 5 years.

Help to keep the rainforest healthy by recycling decaying vegetation.

Hissing Cockroaches force air through small breathing holes called “spiracles” to make a hissing sound which frightens off predators.
