How to calculate air temperature from a cricket's chirp rate

Because they are cold-blooded animals, crickets' metabolic rates are closely linked to the temperature of their surroundings. An interesting side-effect of this is that you can calculate air temperature based on the number of times a cricket chirps per minute: just divide by 4 and then add 40 to get the temperature in Fahrenheit. So 120 chirps per minute translates to 70 degrees F.
