Rare
Under 5% of wildlife watchers report a Rufous-Backed Cellophane Bee sighting in Boston on a given day, based on 29 verified sightings from GBIF citizen-science data. It is the 386th 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.
May and June
In those months about 10% of wildlife watchers report a Rufous-Backed Cellophane Bee in Boston on a given day, against under 5% in July to April, the lowest months.
Between 10 am and 1 pm
Across all the parks we cover, that three-hour window holds the most Rufous-Backed Cellophane Bee sightings with a recorded time, and nearly all of them come between 6 am and 6 pm: it is a daytime animal.
Among the best
Of the 5 cities where we can rate Rufous-Backed Cellophane Bee sightings, Boston ranks 4th at under 5%, level with the leaders once rounded. The best odds are in Washington (United States, under 5%), New York City (United States, under 5%) and Philadelphia (United States, under 5%).
GBIF citizen-science records
It is estimated from how often the Rufous-Backed Cellophane Bee is recorded against all the insects logged in Boston (29 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.
