Dendarus coarcticollis
In 3 days ~30% in a week ~60%
Dendarus coarcticollis is a species of darkling beetles belonging to the family Tenebrionidae subfamily Tenebrioninae. These beetles are mainly present in France and Italy. The adults grow up to 12–13 millimetres (0.47–0.51 in) long. The front legs in males are larger than in females, sexual dimorphism that allows males of these terrestrial and often dirty and slippery beetles to better hold on to the back of females. They are nocturnal. They usually overwinter under the bark of an old tree. Wikipedia →

GBIF citizen-science records
It is estimated from how often the Dendarus coarcticollis is recorded against all the insects logged in Mercantour National Park (10 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.
