Rare
Under 5% of wildlife watchers report a Peacock Fly sighting in Philadelphia on a given day, based on 15 verified sightings from GBIF citizen-science data. It is the 313th 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 Peacock Fly in Philadelphia on a given day, so our monthly data shows no clear season.
Between 1 and 4 pm
Across all the parks we cover, that three-hour window holds the most Peacock Fly sightings with a recorded time, and nearly all of them come between 6 am and 6 pm: it is a daytime animal.
6th of 13
Of the 13 cities where we can rate Peacock Fly sightings, Philadelphia ranks 6th at under 5%. The best odds are in Berlin (Germany, about 10%), Warsaw (Poland, about 10%) and Bucharest (Romania, under 5%).
GBIF citizen-science records
It is estimated from how often the Peacock Fly is recorded against all the insects logged in Philadelphia (15 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.
