Overview
The Common Green Grasshopper is the most numerous grasshopper of the Sefton Coast dune grassland. As the name suggests, both sexes are predominantly green, though there is variation — some individuals are more grey-brown. The male's song is a series of soft, rising 'tik' notes building to a sustained purring churr, repeated every 20–30 seconds. On warm July afternoons, the sound fills the dune grassland. They jump enormous distances relative to their size when disturbed.

Frequently Asked Questions
How do grasshoppers make their sound?
Grasshoppers stridulate by rubbing a row of pegs on the inner surface of the hind legs against the edge of the forewing — the leg acting like a comb on a ridged surface. Each species has a characteristic song. On warm summer days in the dune grassland, the sound of multiple species singing simultaneously creates one of the characteristic soundscapes of the Sefton Coast.
