Rare
Under 5% of wildlife watchers report an Archarius pyrrhoceras sighting in London on a given day, based on 13 verified sightings from GBIF citizen-science data. It is the 1059th most-seen of the 1504 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.

Across all the parks we cover, that three-hour window holds the most Archarius pyrrhoceras sightings with a recorded time, and nearly all of them come between 6 am and 6 pm: it is a daytime animal.
Only London, in our data

GBIF citizen-science records
It is estimated from how often the Archarius pyrrhoceras is recorded against all the insects logged in London (13 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.
