Omocestus viridulus, known in the British Isles as the common green grasshopper, is a Palearctic species of grasshopper in the subfamily Gomphocerinae. Omocestus viridulus are usually green all over, but some may have brown coloration on the sides. In Scandinavia, they are usually green or light brown. The males do not have any red coloring on the abdomen and possess a noticeably long ovipositor, characteristics that help distinguish it from the similar species O. rufipes and O. haemorrhoidalis. The eyes of this species may be brown or yellow. The typical body length is 17–20 millimetres (0.67–0.79 in). They possess a strongly darkened region of the hind wing.
Omocestus viridulus typically lives in moderately wet regions around Europe except north of the Arctic Circle, and it is distributed widely over Britain. Its range extends east as far as Siberia and Mongolia. Their preferred habitat consists of areas with longer grass.
This species prefers to feed on the more common, abundant grass species and this may promote greater diversity of vegetation. O. viridulus feeds on grass from the genera Dactylis, Agrostis... Wikipedia →

GBIF citizen-science records
It is estimated from how often the Common Green Grasshopper is recorded against all the insects logged in Pyrénées National Park (63 verified sightings from 2019 to 2026), calibrated against known sighting rates. Figures are rounded to the nearest 10% because citizen-science data supports honest approximations, not decimals, and months with records from fewer than five people show "—". How it works.
