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 →

Possible
About 30% of wildlife watchers report a Common Green Grasshopper sighting in Mercantour National Park on a given day, based on 64 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 26th most-seen of the 412 insects we can rate there. Over three days the chance rises to about 70%, and over a week to about 90%, if each day is a fresh chance.
September
In that month about 50% of wildlife watchers report a Common Green Grasshopper in Mercantour National Park on a given day, against under 5% in January to May, the lowest months.
Between 1 and 4 pm
Across all the parks we cover, that three-hour window holds the most Common Green Grasshopper sightings with a recorded time, and nearly all of them come between 6 am and 6 pm: it is a daytime animal.
Yes
Of the 12 parks where we can rate Common Green Grasshopper sightings, Mercantour National Park has the highest daily chance: about 30%. Next come Tatra National Park (Slovakia, about 20%) and Hohe Tauern National Park (Austria, about 20%).

GBIF citizen-science records
It is estimated from how often the Common Green Grasshopper is recorded against all the insects logged in Mercantour National Park (64 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.
