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 →

With luck
About 10% of wildlife watchers report a Common Field Grasshopper sighting in Bavarian Forest National Park on a given day, based on 20 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 248th most-seen of the 1115 insects we can rate there. Over three days the chance rises to about 20%, and over a week to about 50%, if each day is a fresh chance.
May to September
In those months about 10% of wildlife watchers report a Common Field Grasshopper in Bavarian Forest National Park on a given day, against under 5% in October to April, 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.
3rd of 6
Of the 6 parks where we can rate Common Field Grasshopper sightings, Bavarian Forest National Park ranks 3rd at about 10%. The best odds are in Snowdonia National Park (United Kingdom, about 20%) and Mercantour National Park (France, about 10%).
GBIF citizen-science records
It is estimated from how often the Common Field Grasshopper is recorded against all the insects logged in Bavarian Forest National Park (20 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.
