# Cricket — Facts, Threats & Conservation

*Gryllidae*

## Key facts: Cricket
- 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.
- Crickets are omnivores that eat plant matter, fungi, and small insects, scavenging a wide range of foods.
- 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.

## 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.

## What WARN does
WARN does not run a dedicated cricket programme — this guide is part of the World Animal Rescue Network's free educational library. The cricket is currently widespread and not globally threatened, and this guide helps readers understand the pressures that can change that. Building public understanding of species like the cricket supports the broader conservation awareness that underpins WARN's partner-led rescue work across its network.

If clear, science-based wildlife guides like this help you understand and value animals, please consider supporting the World Animal Rescue Network's educational and rescue work so we can keep producing them.

## Frequently asked questions: Cricket
### Why do crickets chirp?
Male crickets chirp to attract females and to ward off other males. They make the sound by rubbing their wings together, a process called stridulation.

### What do crickets eat?
Crickets are omnivores that eat plant material, fungi, and small insects. They are scavengers that will feed on a wide variety of organic matter.

### How long do crickets live?
Most crickets live for about a year or less. They hatch as nymphs, grow through several molts, and the adults usually die off after the breeding season.

### Can you eat crickets?
Yes. Crickets are edible and are farmed as a protein source for people in some parts of the world. They are also widely raised as food for pet reptiles, amphibians, and birds.

### Do crickets bite?
Large crickets can give a small nip if handled, but they are harmless to people. They have no venom and rely on jumping to escape rather than biting in defense.

### What is the difference between a cricket and a grasshopper?
Crickets and grasshoppers are related jumping insects, but crickets usually have longer antennae, are active mainly at night, and chirp by rubbing their wings, while grasshoppers are active by day and rub a leg against a wing.

### Where do crickets live?
Crickets live in Grasslands, forests, gardens, buildings. 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.

### Are crickets dangerous?
Crickets are not generally dangerous to people. 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. Give wild individuals space and do not corner or handle them.

### How big is a cricket?
A Cricket is about About 1 year or less. 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. Conservation status: Least Concern (IUCN).
