In 3 days ~10% in a week ~20%
Cucujus cinnaberinus is a species of beetles in the family Cucujidae, the flat bark beetles. It is native to Europe, being most common in Central Europe and rare in much of Southern and Western Europe. This beetle lives under tree bark. It is associated with oaks (Quercus spp.), maples (Acer spp.), and poplars (Populus spp.). It can be found in various habitat types, including forests and urban areas. It is a saproxylic species, often feeding on decomposing wood. It has also been observed eating maggots and the larvae of other beetles.
This beetle is on the IUCN Red List as a near-threatened species. It is on many national lists of threatened species in Europe. Forest management practices include the removal of dead wood and dying trees, reducing available habitat and food sources for the beetle. Wikipedia →

Rare
Under 5% of wildlife watchers report a Cucujus cinnaberinus sighting in Vienna on a given day, based on 10 verified sightings from GBIF citizen-science data. It is the 895th most-seen of the 1406 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.
Any time of year
In every month with enough records, under 5% of wildlife watchers report a Cucujus cinnaberinus in Vienna on a given day, so our monthly data shows no clear season.
Between 10 am and 1 pm
Across all the parks we cover, that three-hour window holds the most Cucujus cinnaberinus sightings with a recorded time, and nearly all of them come between 6 am and 6 pm: it is a daytime animal.
Yes
Of the 2 cities where we can rate Cucujus cinnaberinus sightings, Vienna has the highest daily chance: under 5%. Next come Moscow (Russia, under 5%).

GBIF citizen-science records
It is estimated from how often the Cucujus cinnaberinus is recorded against all the insects logged in Vienna (10 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.
