Chorthippus albomarginatus
In 3 days ~30% in a week ~50%
Chorthippus albomarginatus, the lesser marsh grasshopper, is a common grasshopper of European grassland both damp-marshy and (despite its name) dry, including salt-marsh and coastal habitats. The range of the lesser marsh grasshopper extends from Finland and southern Scandinavia in the north to Spain and Italy in the south. It was once present only in the southern parts of the UK but has been expanding its range northwards.
Females grow to approximately 20 millimetres (0.8 in) and are larger than males which grow to approximately 15 mm (0.6 in). The female almost always has a longitudinal white stripe on the wing whereas the male rarely does.
The region behind the head is referred to as the "pronotal side-keels" and the bars are approximately parallel in this species. Although quite similar, it can be distinguished from the meadow grasshopper Chorthippus parallelus, which also has straight pronotal side-keels, by several characteristics. These include its ability to fly, a white stripe on the female's wing, and a more pointed snout. It often tends to be less brightly coloured and more straw-brown than Chorthippus parallelus.

About 10% of wildlife watchers report a Lesser Marsh Grasshopper sighting in Birmingham on a given day, based on 64 verified sightings from GBIF citizen-science data. It is the 178th most-seen of the 811 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.

GBIF citizen-science records
It is estimated from how often the Lesser Marsh Grasshopper is recorded against all the insects logged in Birmingham (64 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.
