In 3 days ~10% in a week ~20%
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 →

Rare
Under 5% of wildlife watchers report an Ocypus ophthalmicus sighting in Lisbon on a given day, based on 6 verified sightings from GBIF citizen-science data. It is the 361st most-seen of the 441 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.
November
In that month about 10% of wildlife watchers report an Ocypus ophthalmicus in Lisbon on a given day, against under 5% in December to October, the lowest months. That is one of Lisbon's wettest months, with about 95 mm of rain against almost none in July.
3rd of 3
Of the 3 cities where we can rate Ocypus ophthalmicus sightings, Lisbon ranks 3rd at under 5%. The best odds are in Lyon (France, about 10%) and Berlin (Germany, under 5%).
GBIF citizen-science records
It is estimated from how often the Ocypus ophthalmicus is recorded against all the insects logged in Lisbon (6 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.
