Eupeodes pomus, the short-tailed aphideater, is a species of syrphid fly observed across North America. Hoverflies can remain nearly motionless in flight. The adults are also known as flower flies for they are commonly found on flowers from which they get both energy-giving nectar and protein-rich pollen. Larvae have been reported feeding from various aphids. Wikipedia →

GBIF citizen-science records
It is estimated from how often the Short-Tailed Aphideater is recorded against all the insects logged in Philadelphia (18 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.
