In 3 days ~40% in a week ~70%
Carabus problematicus is a species of beetle endemic to Europe, where it is observed in Andorra, Austria, Belgium, Great Britain, the Czech Republic, mainland Denmark, the Faroe Islands, Finland, mainland France, Germany, Hungary, Iceland, Ireland, mainland Italy, Latvia (doubtful), Liechtenstein, Luxembourg, mainland Norway, Poland, Romania, northern and northwestern Russia, Slovakia, Slovenia, mainland Spain, Sweden, Switzerland, and the Netherlands.
A study of the effects of grazing management on arthropod distribution observed high number clusters of C. problematicus associated with the sheep rather than sheep and cattle grazed plots – suggesting that there are detrimental effects of cattle to the species; possibly as a result of soil compaction.

GBIF citizen-science records
It is estimated from how often the Rough Violet Ground Beetle is recorded against all the insects logged in Cairngorms National Park (34 verified sightings from 2019 to 2026), 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.
