Chorthippus vagans, which may be called the heath grasshopper or steppe grasshopper, is a species of grasshopper belonging to the subfamily Gomphocerinae. It is found across the Palearctic through Russia and Kazakhstan, east to Siberia, and north to Denmark. It is rare in the British Isles.
In Central Europe they are usually found at altitudes of 300 to 600 m (980 to 1,970 ft). In the French Calcareous Alps, the species is found on Mont Ventoux up to an altitude of 1,900 m (6,200 ft). The steppe grasshopper lives in warm and dry habitats with sparse, low vegetation. Wikipedia →

Under 5% of wildlife watchers report a Heath Grasshopper sighting in Porto on a given day, based on 8 verified sightings from GBIF citizen-science data. It is the 377th most-seen of the 498 insects we can rate there. Over three days the chance rises to about 10%, and over a week to about 20%, if each day is a fresh chance.
July–August and October
In those months about 10% of wildlife watchers report a Heath Grasshopper in Porto on a given day, against under 5% in September and November–June, the lowest months.

Across all the parks we cover, that three-hour window holds the most Heath 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 2 cities where we can rate Heath Grasshopper sightings, Porto has the highest daily chance: under 5%. Next come Lisbon (Portugal, under 5%).
GBIF citizen-science records
It is estimated from how often the Heath Grasshopper is recorded against all the insects logged in Porto (8 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.
