The tree cricket Oecanthus fultoni. Dolbear's law states the relationship between the air temperature and the rate at which crickets chirp. [1] [2] It was formulated by physicist Amos Dolbear and published in 1897 in an article called "The Cricket as a Thermometer". [3]
Crickets are mainly nocturnal, and are best known for the loud, persistent, chirping song of males trying to attract females, although some species are mute. The singing species have good hearing, via the tympana on the tibiae of the front legs. Crickets often appear as characters in literature.

The chirp (or trill) of a tree cricket is long and continuous and can sometimes be mistaken for the call of a cicada or certain species of frogs. While male tree crickets have the ability to call, females lack the ability. [5] This call is then received by other tree crickets in the area through a system called sender-receiver matching.
Unlike females, however, males are able to produce sounds or chirps. Thus, males can be identified through sound while females cannot. Diagram A shows the male cricket with its wings raised for the purpose of chirping. Diagram B shows the female cricket, identified via the long protruding ovipositor at the end of the abdomen.
The anatomical parts used to produce sound are quite varied: the most common system is that seen in grasshoppers and many other insects, where a hind leg scraper is rubbed against the adjacent forewing (in beetles and true bugs the forewings are hardened); in crickets and katydids a file on one wing is rubbed by a scraper on the other wing; in ...
