In addition, members of this group possess opaque, leather-like forewings that cover a pair of clear, membranous hindwings.
Most crickets are nocturnal, whereas their grasshopper cousins are active only during the daytime.
Crickets may be distinguished from cockroaches by their enlarged hind legs and the fact that their bodies are not flattened from top to bottom like those of cockroaches. The chirp's function is to attract the female cricket to the male. Each species has a characteristic chirp that is recognized and responded to only by females of the same species. The membrane picks up the vibrations of the chirp and transmits them to a sensory nerve, which relays the message to the brain. Once the female cricket is mated, she seeks loose, friable soil in which to deposit her eggs.
