Chorthippus albomarginatus
In 3 days ~20% in a week ~40%
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.

With luck
About 10% of wildlife watchers report a Lesser Marsh Grasshopper sighting in London on a given day, based on 68 verified sightings from GBIF citizen-science data. It is the 398th most-seen of the 1504 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.
July to September
In those months about 10% of wildlife watchers report a Lesser Marsh Grasshopper in London on a given day, against under 5% in October to June, the lowest months.
Between noon and 3 pm
Across all the parks we cover, that three-hour window holds the most Lesser Marsh 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.
Among the best
Of the 8 cities where we can rate Lesser Marsh Grasshopper sightings, London ranks 3rd at about 10%, level with the leaders once rounded. The best odds are in Birmingham (United Kingdom, about 10%) and Hamburg (Germany, about 10%).
GBIF citizen-science records
It is estimated from how often the Lesser Marsh Grasshopper is recorded against all the insects logged in London (68 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.
