Chorthippus biguttulus, the bow-winged grasshopper, is one of the most common species of grasshopper found in the dry grassland of northern and central Europe. It is part of a group of species (biguttulus-group) that are very difficult to identify morphologically. Chorthippus biguttulus was previously classified (with C. brunneus and C. mollis) as a single species Stauroderus variabilis. The three species were distinguished using song characteristics.
The range of the bow-winged grasshopper extends from the Finland and Scandinavia in the north to the Alps and Pyrenees in the south, and goes well into Asia including Japan. Females grow to approximately 2 cm (0.79 in) and are larger than males that grow to approximately 1.5 cm (0.59 in). Males often have a red tip to the abdomen while females do not. They can be extremely variable in colour from green to black-brown to rose.
C. brunneus, C. bigguttulus and C. mollis are morphologically distinguished by the size of the costal and subcostal fields of the wings. They are more easy recognised by their song patterns. Female C. biguttulus appear to be able to integrate information... Wikipedia →

With luck
About 10% of wildlife watchers report a Bow-Winged Grasshopper sighting in Novosibirsk on a given day, based on 14 verified sightings from GBIF citizen-science data. It is the 78th most-seen of the 216 insects we can rate there. Over three days the chance rises to about 20%, and over a week to about 40%, if each day is a fresh chance.
June to September
In those months about 10% of wildlife watchers report a Bow-Winged Grasshopper in Novosibirsk on a given day, against under 5% in October to May, the lowest months.
Between 1 and 4 pm
Across all the parks we cover, that three-hour window holds the most Bow-Winged Grasshopper sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Yes
Of the 7 cities where we can rate Bow-Winged Grasshopper sightings, Novosibirsk has the highest daily chance: about 10%. Next come Helsinki (Finland, about 10%) and Vienna (Austria, about 10%).
GBIF citizen-science records
It is estimated from how often the Bow-Winged Grasshopper is recorded against all the insects logged in Novosibirsk (14 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.
