Rare
Under 5% of wildlife watchers report a Black-And-Gray Leafcutter Bee sighting in Seattle on a given day, based on 7 verified sightings from GBIF citizen-science data. It is the 332nd most-seen of the 428 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 a Black-And-Gray Leafcutter Bee in Seattle on a given day, so our monthly data shows no clear season.
Among the best
Of the 3 cities where we can rate Black-And-Gray Leafcutter Bee sightings, Seattle ranks 3rd at under 5%, level with the leaders once rounded. The best odds are in Vancouver (Canada, under 5%) and Calgary (Canada, under 5%).
GBIF citizen-science records
It is estimated from how often the Black-And-Gray Leafcutter Bee is recorded against all the insects logged in Seattle (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.
