Common green grasshopper (likely)

Grassland, heathland, meadows and rough vegetation throughout much of Britain; adults are active in September, though declining late in the season.

Primarily grasses and other herbaceous plants, feeding by chewing leaves.

Mostly day-active and flight-capable, often basking or jumping when disturbed. Eggs are laid in soil or plant debris; adults generally persist into early autumn.

Harmless to people and not a significant household or crop pest. It contributes to food webs as prey for birds, reptiles and small mammals, although the identification is tentative because the image is a screen photograph and key markings are partly obscured.
