Chorthippus brunneus, also known as the common field grasshopper, is a species of grasshopper of the subfamily Gomphocerinae. The species is common and widespread in the Western Palearctic, and the IUCN lists it as Least Concern.
C. brunneus are predominantly brown. However, they show a large variation in colour and can also be black, green, purple, or white. Wing patterns vary between individuals and can be mottled, striped, striped-mottled, or plain. Both green and purple grasshoppers tend to have plain forewing patterns while black grasshoppers primarily have mottled forewing patterns. Brown grasshoppers do not consistently have the same forewing pattern instead they have variable forewing patterns.
At least two loci are responsible for pronotum color in C. brunneus. Green alleles are dominant to all other colors while brown alleles are recessive to all other colors. Wing pattern is determined by a separate locus than colour. The plain forewing pattern is dominant and the striped and mottled forewing patterns are codominant.
C. brunneus are found in Europe, north Africa, and temperate Asia. They prefer dry habitats. They are present in higher... Wikipedia →

Rare
Under 5% of wildlife watchers report a Common Field Grasshopper sighting in Pyrénées National Park on a given day, based on 13 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 703rd most-seen of the 1277 insects we can rate there. Over three days the chance rises to about 10%, and over a week to about 30%, if each day is a fresh chance.
April, August and October
In those months about 10% of wildlife watchers report a Common Field Grasshopper in Pyrénées National Park on a given day, against under 5% in May–July, September and November–March, the lowest months.
Between 11 am and 2 pm
Across all the parks we cover, that three-hour window holds the most Common Field Grasshopper sightings with a recorded time, and about 8 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
6th of 6
Of the 6 parks where we can rate Common Field Grasshopper sightings, Pyrénées National Park ranks 6th at under 5%. The best odds are in Snowdonia National Park (United Kingdom, about 20%), Mercantour National Park (France, about 10%) and Bavarian Forest National Park (Germany, about 10%).
Same genus: Chorthippus
The closest relatives of the Common Field Grasshopper that you can see in Pyrénées National Park (genus Chorthippus, Eurasian Field Grasshoppers) are French Grasshopper (about 10%), Locomotive Grasshopper (about 10%) and Steppe Grasshopper (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Common Field Grasshopper is recorded against all the insects logged in Pyrénées National Park (13 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.
