stridulatory organs

In insects, organs that produce sound when rubbed together. Crickets rub their wings together, but grasshoppers rub a hind leg against a wing. Stridulation is thought to be used for attracting mates, but may also serve to mark territory.

Temperatures can be determined from the stridulations of crickets: adding 40 to the number of chirps counted in 15 seconds gives the approximate temperature in Fahrenheit.
