In 3 days ~20% in a week ~30%
Ocypus ophthalmicus is a species of rove beetle belonging to the family Staphylinidae, subfamily Staphylininae. These beetles are present in most of Europe, in the eastern Palearctic realm, in North Africa, and in the Near East.
Its head, pronotum, and elytra have metallic blue reflections, with a shiny surface of pronotum. The adults grow up to 17–22 mm (0.67–0.87 in) long. O. ophthalmicus is a eurytopic species and can be encountered both in deciduous forests (Quercus spp., Fagus spp.) and in xeric habitats. Generally, they are found in detritus, under stones, and on dung. They are nocturnal predators (especially of worms, snails, larvae, etc.).
They are known for their habit of raising their long abdomens and opening their jaws, like a threatened scorpion. In this defense posture, they secrete an irritating substance, with a very unpleasant smell. Wikipedia →

GBIF citizen-science records
It is estimated from how often the Ocypus ophthalmicus is recorded against all the insects logged in Lyon (9 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.
