Rare
Under 5% of wildlife watchers report a Band-Winged Crane Fly sighting in Washington on a given day, based on 23 verified sightings from GBIF citizen-science data. It is the 827th most-seen of the 1807 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 Band-Winged Crane Fly in Washington 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 Band-Winged Crane Fly sightings with a recorded time, and about 6 in 10 of them come between 6 am and 6 pm: it is seen both by day and at night.
Among the best
Of the 8 cities where we can rate Band-Winged Crane Fly sightings, Washington ranks 5th at under 5%, level with the leaders once rounded. The best odds are in Montreal (Canada, under 5%), Toronto (Canada, under 5%) and Boston (United States, under 5%).
GBIF citizen-science records
It is estimated from how often the Band-Winged Crane Fly is recorded against all the insects logged in Washington (23 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.
