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 Vienna on a given day, based on 167 verified sightings from GBIF citizen-science data. It is the 88th most-seen of the 1406 insects we can rate there. Over three days the chance rises to about 30%, and over a week to about 50%, if each day is a fresh chance.
July
In that month about 20% of wildlife watchers report a Common Field Grasshopper in Vienna on a given day, against under 5% in December to May, the lowest months. That is one of Vienna's wettest months, with about 90 mm of rain against 40 mm in February.
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.
5th of 27
Of the 27 cities where we can rate Common Field Grasshopper sightings, Vienna ranks 5th at about 10%. The best odds are in Liverpool (United Kingdom, about 20%), Birmingham (United Kingdom, about 20%) and London (United Kingdom, about 20%).
Same genus: Chorthippus
The closest relatives of the Common Field Grasshopper that you can see in Vienna (genus Chorthippus, Eurasian Field Grasshoppers) are Steppe Grasshopper (about 10%) and Bow-Winged 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 Vienna (167 verified sightings), 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.
