Rare
Under 5% of wildlife watchers report a Winter Firefly sighting in Philadelphia on a given day, based on 6 verified sightings from GBIF citizen-science data. It is the 510th most-seen of the 632 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 Winter Firefly in Philadelphia on a given day, so our monthly data shows no clear season.
Between noon and 3 pm
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.
7th of 7
Of the 7 cities where we can rate Winter Firefly sightings, Philadelphia ranks 7th at under 5%. The best odds are in Boston (United States, about 20%), 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 Philadelphia (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.
