Quick answer
Crickets are jumping insects closely related to grasshoppers, best known for the chirping sound males make to attract mates. They are mostly active at night and feed on plants, fungi, and small insects. Crickets are also widely raised as food for pets and, increasingly, for people. Most live for about a year or less.

Biology
Cricket (Gryllidae) is classified as Insect with conservation status Least Concern. Typical weight about 0.0005 kg; lifespan around About 1 year or less.
Ecology
Diet: Omnivore (plants, fungi, small insects). Habitat: Grasslands, forests, gardens, buildings. Movement and social systems reflect those pressures.
People and this species
Learn before you travel or keep related pets. Wild individuals are not toys; captive care needs species-specific husbandry.

The familiar chirp
The chirping associated with crickets is made mostly by males, who rub a sharp edge on one wing against a rough surface on the other, a process called stridulation. The calls attract females and warn off rival males. Because chirping rate rises with temperature, the calls can even give a rough sense of how warm it is.
Diet and behavior
Crickets are omnivores that eat plant matter, fungi, and small insects, scavenging a wide range of foods. They are mostly active at night, hiding by day under stones, logs, or vegetation. Like their grasshopper relatives, crickets have strong hind legs and can jump to escape danger.
Crickets and people
Crickets are raised in large numbers as a reliable food source for pet reptiles, amphibians, and birds, and they are increasingly farmed as a protein source for human food in some regions. In several cultures their chirping is seen as a pleasant sound or even a sign of good luck.
Life cycle and habitat
Crickets develop through incomplete metamorphosis, hatching as nymphs that resemble small wingless adults and molting as they grow. They live in grasslands, forests, gardens, and sometimes inside buildings, and are found across much of the world in warmer climates.
Research notes
Figures for crickets (Gryllidae) come from field studies, museum records, and conservation assessments that do not always agree on exact averages. Prefer ranges over single-point claims, and check whether a source describes wild, captive, or mixed populations.
Practical takeaways
If you encounter crickets in the wild, prioritise distance and local guidance. If you care for related domestic or captive animals, match diet and housing to species needs rather than generic pet advice. Share accurate status information (Least Concern) when discussing conservation.
