Capsus ater is found in dry to moderately moist, open to partially shaded habitats In the Alps it rises to over 2000 meters above sea level. The bugs live on different grasses (Poaceae) and do not seem to have any particular preference for certain species or genera. Wikipedia →

GBIF citizen-science records
It is estimated from how often the Black Plant Bug is recorded against all the insects logged in Helsinki (7 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.
