Rare
Under 5% of wildlife watchers report a Discomyza incurva sighting in Montreal on a given day, based on 7 verified sightings from GBIF citizen-science data. It is the 694th most-seen of the 926 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 Discomyza incurva in Montreal on a given day, so our monthly data shows no clear season.
Among the best
Of the 4 cities where we can rate Discomyza incurva sightings, Montreal ranks 3rd at under 5%, level with the leaders once rounded. The best odds are in Helsinki (Finland, under 5%) and Vienna (Austria, under 5%).

GBIF citizen-science records
It is estimated from how often the Discomyza incurva is recorded against all the insects logged in Montreal (7 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.
