Madagascar Hissing Cockroach
Did You Know?
- Unlike other insects, these cockroaches make noise by forcing air out of breathing pores, called spiracles, on their abdomen. Hissing is used as part of their mating ritual.
- Males have horn-like bumps behind their head which are used to ram rivals. Winning cockroaches hiss more than the loser. This noise may be used to determine hierarchy.
