A coordinated group of male crickets calling together is known as a chorus.
Male crickets produce songs by rubbing a file on one forewing against a scraper on the other. The song attracts females and helps establish the caller’s identity. When many males call in the same area, their overlapping sounds form a chorus that can dominate the nighttime soundscape.
Cricket choruses are not always perfectly synchronized. Timing can vary among species, and nearby males may adjust their calls in response to one another. In some insects, coordinated timing reduces masking between individual signals, while in others it may simply result from dense calling groups.
The word chorus is also used for collective calling in frogs and some birds, so it does not identify one specific insect species. It is different from the mechanism of stridulation: stridulation describes how a cricket makes its individual sound, whereas chorus describes the combined vocal display of many callers.
