Rare
Under 5% of wildlife watchers report a Distinct Quaker sighting in Boston on a given day, based on 22 verified sightings from GBIF citizen-science data. It is the 547th most-seen of the 1200 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.
April and May
In those months about 10% of wildlife watchers report a Distinct Quaker in Boston on a given day, against under 5% in June to March, the lowest months.
Yes
Of the 5 cities where we can rate Distinct Quaker sightings, Boston has the highest daily chance: under 5%. Next come Toronto (Canada, under 5%) and Dallas (United States, under 5%).
GBIF citizen-science records
It is estimated from how often the Distinct Quaker is recorded against all the insects logged in Boston (22 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.
