Grasshopper

Grasshopper facts at a glance

How big is a grasshopper?

An adult grasshopper measures 4 cm long — about 2% of the height of an average adult person (1.73 m) — and weighs around 0 g, a small fraction of an average adult’s body weight (70 kg).

Powerful jumpers

Grasshoppers have large, muscular hind legs that store energy like a spring, letting them launch into leaps many times their own body length. Jumping helps them escape predators quickly, and many species can also fly to cover longer distances. The legs are the grasshopper's most distinctive feature.

Diet and feeding

Grasshoppers are herbivores that feed on grasses, leaves, and other plants using strong chewing mouthparts. Most cause little harm, but when conditions allow certain species to gather in huge numbers as swarming locusts, they can strip crops and become serious agricultural pests.

Sound and senses

Many grasshoppers produce a chirping or buzzing sound, often by rubbing a hind leg against a wing, a behavior called stridulation. These calls are used mainly to attract mates. Grasshoppers hear through simple ear-like organs located on the body rather than the head.

Life cycle and habitat

Grasshoppers develop through incomplete metamorphosis, hatching as small wingless nymphs that grow through several molts into winged adults. They are found in grasslands, meadows, and fields on most continents, and are an important food source for birds, reptiles, and other animals.

Did you know? Grasshopper facts

• Grasshoppers are plant-eating insects famous for their powerful hind legs, which let them leap many times their own body length.
• Grasshoppers can leap around 20 times their own body length thanks to their powerful spring-like hind legs. For a human, that would be like jumping the length of several buses.
• Grasshoppers are herbivores that feed on grasses, leaves, and stems. Most eat small amounts, but swarming species known as locusts can damage crops over wide areas.
• Many grasshoppers chirp by rubbing a hind leg against a wing, a process called stridulation. These sounds are mainly used by males to attract mates.
• Locusts are certain grasshopper species that can change behavior and form massive migrating swarms when crowded. Otherwise they are closely related plant-eating insects.
• Conservation: Least Concern (IUCN).

Communication

• Grasshopper uses scent, posture, and vocal signals to mark territory and coordinate social behaviour.
• Communication intensity often peaks during breeding seasons and territorial disputes.

Habitat & range

Grasslands, meadows, fields, scrub

Ecological role

Grasshopper shapes vegetation through grazing or browsing and serves as prey for larger predators where ranges overlap.
