It is the 7th most-seen of the 1504 insects we can rate there. Over three days the chance rises to about 70%, and over a week to over 90%, if each day is a fresh chance.
April
In that month about 50% of wildlife watchers report a Common Carder Bumble Bee in London on a given day, against under 5% in December and January, the lowest months.

GBIF citizen-science records
It is estimated from how often the Common Carder Bumble Bee is recorded against all the insects logged in London (1,665 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.
