About 20% of wildlife watchers report a Winter Firefly sighting in Boston on a given day, based on 955 verified sightings from GBIF citizen-science data. It is the 7th most-seen of the 1200 insects we can rate there. Over three days the chance rises to about 50%, and over a week to about 80%, if each day is a fresh chance.
March and April
In those months about 40% of wildlife watchers report a Winter Firefly in Boston on a given day, against under 5% in July, the lowest month.

Across all the parks we cover, that three-hour window holds the most Winter Firefly sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.

Of the 7 cities where we can rate Winter Firefly sightings, Boston has the highest daily chance: about 20%. Next come Montreal (Canada, under 5%) and New York City (United States, under 5%).
GBIF citizen-science records
It is estimated from how often the Winter Firefly is recorded against all the insects logged in Boston (955 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.
