Common field grasshopper description

This is probably the most frequently seen grasshopper; it is fairly large and occurs in a very wide range of colours including green, brown and purple, usually with a variable amount of black, brown or grey mottling ⁽³⁾. The tough forewings, which protect the delicate membranous hind wings, are long, and in common with all Chorthippus species, have a bulge near their base. Most individuals have an orange tinge at the tip of the abdomen ⁽³⁾. This species can be identified by the low number of 'stridulatory' pegs on the legs used to produce the very characteristic song ⁽⁴⁾.

Size

Length: 18 - 24 mm ⁽²⁾

Common field grasshopper biology

This grasshopper is a strong flier, and is active in warm weather ⁽³⁾; on warm days it can frequently be seen sunning itself on walls, bare ground and paths ⁽¹⁾. The song consists of chirps lasting half a second long. Males often chirp at each other in turn; these 'rivalry' songs are very characteristic of the species ^{(4) (5)}. During courtship they produce a 'ticking' sound when paired with a female ⁽³⁾. These sounds are produced by 'stridulation', in which the hindlegs are scraped against veins on the forewing ⁽⁶⁾.

During summer, females lay a large egg pod containing up to 15 eggs in dry ground just below the surface, or sometimes in anthills. The eggs, which are the overwintering stage ⁽¹⁾, hatch in May and adults appear in June. Grasshoppers undergo a type of development known as 'incomplete metamorphosis' in which the larvae, known as 'nymphs', resemble wingless adults, and progress through a series of moults before reaching maturity ⁽⁶⁾. Adult common field grasshoppers are better able to survive cold weather than many other species of grasshopper, and they can occasionally survive until December ⁽³⁾.

Common field grasshopper range

Common throughout Britain ⁽¹⁾, and found throughout Europe including the Iberian Peninsula. It is more common in the north of its range ⁽⁴⁾.

Glossary

Incomplete metamorphosis

Type of insect development (also known as hemimetabolous development) in which the adult form is reached via a series of moults. The larva (nymph) resembles a miniature wingless adult; the wings develop externally as the nymph grows.

Larvae

Stage in an animal's lifecycle after it hatches from the egg. Larvae are typically very different in appearance to adults; they are able to feed and move around but usually are unable to reproduce.

Stridulation

Production of sound by rubbing a file across a membrane. In insects, often a file on a wing rubs against the surface of the other wing, or the file is on a leg which is scraped on the wing.
