Rare
Under 5% of wildlife watchers report a Black-Footed Globetail sighting in Boston on a given day, based on 6 verified sightings from GBIF citizen-science data. It is the 967th 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.
Any time of year
In every month with enough records, under 5% of wildlife watchers report a Black-Footed Globetail in Boston on a given day, so our monthly data shows no clear season.
Between 10 am and 1 pm
Across all the parks we cover, that three-hour window holds the most Black-Footed Globetail 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 4 cities where we can rate Black-Footed Globetail sightings, Boston ranks 3rd at under 5%, level with the leaders once rounded. The best odds are in Montreal (Canada, under 5%) and Calgary (Canada, under 5%).
GBIF citizen-science records
It is estimated from how often the Black-Footed Globetail is recorded against all the insects logged in Boston (6 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.
