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 →

Rare
Under 5% of wildlife watchers report a Common Green Grasshopper sighting in Wadden Sea National Park on a given day, based on 5 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 699th most-seen of the 818 insects we can rate there. Over three days the chance rises to about 10%, and over a week to about 20%, if each day is a fresh chance.
August
In that month about 10% of wildlife watchers report a Common Green Grasshopper in Wadden Sea National Park on a given day, against under 5% in September to July, 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.
12th of 12
Of the 12 parks where we can rate Common Green Grasshopper sightings, Wadden Sea National Park ranks 12th at under 5%. The best odds are in Mercantour National Park (France, about 30%), Tatra National Park (Slovakia, about 20%) and Hohe Tauern National Park (Austria, about 20%).
Same family: Acrididae
The closest relatives of the Common Green Grasshopper that you can see in Wadden Sea National Park (family Acrididae, Short-horned Grasshoppers) are Mottled Grasshopper (about 10%), Lesser Marsh Grasshopper (about 10%) and Common Field Grasshopper (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Common Green Grasshopper is recorded against all the insects logged in Wadden Sea National Park (5 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.
