Eristalis flavipes, the orange-legged drone fly, is a species of hoverfly native to North America. It flies from early April to mid-October, and occurs in a wide variety of habitats, particularly wetlands. Hoverflies get their names from the ability to remain nearly motionless while in flight. The adults are also known as flower flies for they are commonly found around and on flowers, from which they get both energy-giving nectar and protein-rich pollen. The larvae are aquatic filter-feeders of the rat-tailed type.
Eristalis flavipes strongly resembles a bumblebee. For terms see Morphology of Diptera. It is 13 to 17 mm long. Head The face, cheeks (gena) and facial stripe are shining black with short yellow pile. The antennae are dark brown and plumose basally. The eyes are broadly contiguous in the male, with eye pile confined mostly to a vertical stripe.
Thorax The mesonotum, pleurae, and scutellum, with very abundant, long, bright yellow pile over shining black except the center of the nearly hairless mesonotum. The scutellum is wholly light yellow. Abdomen The abdomen is a deep shining black with the second segment dark red and covered with long black hairs with... Wikipedia →

GBIF citizen-science records
It is estimated from how often the Orange-Legged Drone Fly is recorded against all the insects logged in Anchorage (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.
