Grasshoppers

Chorthippus brunneus

Common field grasshopper

This grasshopper sings by rubbing its hind legs against its forewings, producing short bursts of ticking chirps that carry across grassland on warm days.

WhereDry grassland, heathland and gardens
Size15 to 25 mm body length
WhenJune to October

The common field grasshopper is mottled brown, sometimes with green or purple tinged individuals, and has a very hairy underside that helps separate it from similar species. Its pronotum bears keels that curve sharply inward, and its wings extend well past the tip of the abdomen, giving it stronger flight than many other grasshoppers.

Adults appear from June and remain active into October in dry, sunny grassland, gardens and waste ground, where they feed on grasses and low plants. Males sing by rubbing their hind legs against their forewings, producing short bursts of chirps to attract mates during the warmest part of the day.
