Rare
Under 5% of wildlife watchers report an Orange-Vented Mason Bee sighting in London on a given day, based on 9 verified sightings from GBIF citizen-science data. It is the 1109th 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.
Any time of year
In every month with enough records, under 5% of wildlife watchers report an Orange-Vented Mason Bee in London on a given day, so our monthly data shows no clear season.
Only London, in our data
London is the only city on Wallace's Line with enough records to rate Orange-Vented Mason Bee sightings: under 5% of wildlife watchers there report one on a given day.

GBIF citizen-science records
It is estimated from how often the Orange-Vented Mason Bee is recorded against all the insects logged in London (9 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.
