They don’t “boo”, but they do “hiss”

This roach’s name comes from the hissing noise it makes when startled. These sounds are made when air is pushed out through spiracles, tiny holes on the sides of their bodies that help them breathe.

The leaf litter layer of the forest provides plenty of food, water, shelter, and space for a happy cockroach.
