Entomology

insects producing sound by rubbing two body parts together, typically a ridged file drawn across a scraper.

In insects, stridulation is the production of sound by rubbing two body parts together, typically a ridged file drawn across a hardened scraper: crickets and katydids rasp file-bearing wings, grasshoppers rub a leg against a wing, to make calling, courtship, and alarm signals. Davis's 1968 Cricket wing movements during stridulation describes the wing stroke that generates the song, and Chapman's The Insects: Structure and Function treats the mechanics of insect sound production. The referent is friction-generated sound from paired cuticular structures, the same construct found in animals far removed from insects.[1][2]

Unit
Sound generated by rubbing a file against a scraper
Recovery means
Not applicable
Measured by
Characterised by the file-and-scraper morphology, the stroke rate, and the frequency and pulse structure of the sound

Ichthyology

A fin spine rubbed in its socket

Fishes stridulate too: many catfishes produce sound by moving the base of a pectoral-fin spine against a grooved socket in the shoulder girdle, generating pulses used in distress and in aggressive encounters. Fine and colleagues' 1996 study of pectoral stridulation in the channel catfish describes the mechanism and even a left–right asymmetry in how the two spines are used. It is the same construct as insect stridulation, sound made by rubbing two hard skeletal parts together, independently evolved in a vertebrate.[3]

Unit
Sound generated by rubbing a pectoral-fin spine in its socket
Recovery means
Not applicable
Measured by
Measured from the spine-and-socket movement and the pulse rate and acoustic structure of the sound
