Rare
Under 5% of wildlife watchers report a European Rhinoceros Beetle sighting in Copenhagen on a given day, based on 7 verified sightings from GBIF citizen-science data. It is the 340th most-seen of the 476 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.
June
In that month about 10% of wildlife watchers report a European Rhinoceros Beetle in Copenhagen on a given day, against under 5% in July to May, the lowest months.

GBIF citizen-science records
It is estimated from how often the European Rhinoceros Beetle is recorded against all the insects logged in Copenhagen (7 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.
