'Crickets chirp at different rates depending on their species and the temperature of their environment.

Most species chirp at higher rates the higher the temperature is (approx. 60 chirps a minute at 13°C in one common species; each species has its own rate).

The relationship between temperature and the rate of chirping is known as Dolbear's Law.

In fact, according to this law, it is possible to calculate the temperature in Fahrenheit by adding 40 to the number of chirps produced in 15 seconds by the snowy tree cricket common in the United States.'
