Bombylius incanus is a species of bee fly in the family Bombyliidae. It was described from Massachusetts in 1907. Bombylius incanus was described by Charles Willison Johnson in 1907 in a review of eastern United States species of Bombylius. It is placed in the subgenus Zephyrectes as Bombylius (Zephyrectes) incanus. The holotype is held in the entomology collection of the Museum of Comparative Zoology and was collected at Provincetown, Massachusetts, on 27 June 1904.
Bombylius incanus is a pale, white-pilose bee fly: the face and cheeks are clothed with white pile, the body pile is mostly white, and the mesonotum and posterior margins of the abdominal tergites bear scattered black to brown pile. The wings are unspotted and extensively darkened basally, with the infuscated basal area gradually blending into the clearer distal portion of the wing.
Its predominantly white pile separates it from similar eastern North American Bombylius species with darker facial pile or more yellowish dorsal pile. Adults measure about 8–10 mm long. Bombylius incanus is a Nearctic bee fly of the eastern United States, recorded from Connecticut... Wikipedia →

Rare
Under 5% of wildlife watchers report a Bombylius incanus sighting in New York City on a given day, based on 12 verified sightings from GBIF citizen-science data. It is the 1034th most-seen of the 1623 insects we can rate there. Over three days the chance rises to about 10%, if each day is a fresh chance.
Any time of year
In every month with enough records, under 5% of wildlife watchers report a Bombylius incanus in New York City on a given day, so our monthly data shows no clear season.
Only New York City, in our data
New York City is the only city on Wallace's Line with enough records to rate Bombylius incanus sightings: under 5% of wildlife watchers there report one on a given day.
GBIF citizen-science records
It is estimated from how often the Bombylius incanus is recorded against all the insects logged in New York City (12 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.
