Rare
Under 5% of wildlife watchers report a Dusky-Winged Hover Fly sighting in Miami on a given day, based on 54 verified sightings from GBIF citizen-science data. It is the 191st most-seen of the 826 insects we can rate there. Over three days the chance rises to about 10%, and over a week to about 30%, if each day is a fresh chance.
April and December
In those months about 10% of wildlife watchers report a Dusky-Winged Hover Fly in Miami on a given day, against under 5% in January–March and May–November, the lowest months. Those are among Miami's driest months, with about 65 mm of rain a month against 190 mm in June.
Between 1 and 4 pm
Across all the parks we cover, that three-hour window holds the most Dusky-Winged Hover Fly sightings with a recorded time, and nearly all of them come between 6 am and 6 pm: it is a daytime animal.
5th of 12
Of the 12 cities where we can rate Dusky-Winged Hover Fly sightings, Miami ranks 5th at under 5%. The best odds are in Houston (United States, about 10%), Washington (United States, under 5%) and Baltimore (United States, under 5%).
GBIF citizen-science records
It is estimated from how often the Dusky-Winged Hover Fly is recorded against all the insects logged in Miami (54 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.
