Rare
Under 5% of wildlife watchers report a Faint-Spotted Angle sighting in Philadelphia on a given day, based on 5 verified sightings from GBIF citizen-science data. It is the 557th 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 Faint-Spotted Angle in Philadelphia on a given day, so our monthly data shows no clear season.
Between 8 and 11 pm
Across all the parks we cover, that three-hour window holds the most Faint-Spotted Angle sightings with a recorded time, and about half of them come between 6 pm and 6 am: it is seen both by day and at night.
Among the best
Of the 4 cities where we can rate Faint-Spotted Angle sightings, Philadelphia ranks 3rd at under 5%, level with the leaders once rounded. The best odds are in Washington (United States, under 5%) and Toronto (Canada, under 5%).
GBIF citizen-science records
It is estimated from how often the Faint-Spotted Angle is recorded against all the insects logged in Philadelphia (5 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.
