Звук погромче! 🔈
Мадагаскарские тараканы и некоторые другие виды примечательны способностью шипеть или свистеть.
Шипение получается от резкого сокращения брюшка, из-за которого воздух с силой проходит через дыхальца.
Девочки шипят только во время опасности. Пацаны шипят, чтоб отпугнуть хищников, во время борьбе за самочку, во время ухаживания и даже спаривания - в общем, хрен заткнёшь. А всё почему? А потому что чем громче пацан шипит, тем выше его шансы на спаривание.

Madagascar hissing cockroach. 🔈

Madagascar hissing cockroach is characterized by its "hissing" sound, which some people claim sounds more like a rattlesnake's tail or a rainstick. This is their primary method of warding off potentially insectivorous predators. The sound is produced as the insect forcefully expels air out of their specialized respiratory spiracles (orifices), mainly those that are located on the insect fourth body segment (abdomen), although spiracles are found, more or less, on all segments of their abdomen. The Madagascar hissing cockroach is the only member of their group of cockroaches that can make audible sounds. Compared to crickets, this exact mode of sound production is atypical, as most insects that make noises do so by rubbing together various body parts ("stridulation"), such as the hind legs. Some long-horned beetles, e.g., the giant Fijian long-horned beetle, hiss by squeezing air out from under their elytra, but this does not involve the spiracles. In hissing cockroaches, the sound takes three forms: the disturbance hiss, the female-attracting hiss, and the aggressive or fighting hiss. All cockroaches from the fourth instar (fourth molting cycle) and older are capable of the disturbance hiss. Only males use the female-attracting hiss and fighting hiss; the latter is used between males to settle territory disputes over breeding rights.
