Rare
Under 5% of wildlife watchers report a Black Duckweed Moth sighting in Toronto on a given day, based on 14 verified sightings from GBIF citizen-science data. It is the 902nd most-seen of the 1689 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 Black Duckweed Moth in Toronto on a given day, so our monthly data shows no clear season.
Among the best
Of the 5 cities where we can rate Black Duckweed Moth sightings, Toronto ranks 4th at under 5%, level with the leaders once rounded. The best odds are in Dallas (United States, under 5%), Boston (United States, under 5%) and Houston (United States, under 5%).
GBIF citizen-science records
It is estimated from how often the Black Duckweed Moth is recorded against all the insects logged in Toronto (14 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.
