About 10% of wildlife watchers report a Monoceros Beetle sighting in Amsterdam on a given day, based on 10 verified sightings from GBIF citizen-science data. It is the 120th most-seen of the 234 insects we can rate there. Over three days the chance rises to about 20%, and over a week to about 40%, if each day is a fresh chance.
May to July

GBIF citizen-science records
It is estimated from how often the Monoceros Beetle is recorded against all the insects logged in Amsterdam (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.
