Rare
Under 5% of wildlife watchers report a Black-Tipped Darner sighting in Toronto on a given day, based on 19 verified sightings from GBIF citizen-science data. It is the 704th 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-Tipped Darner in Toronto on a given day, so our monthly data shows no clear season.
Between 1 and 4 pm
Across all the parks we cover, that three-hour window holds the most Black-Tipped Darner sightings with a recorded time, and about 7 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Yes
Of the 2 cities where we can rate Black-Tipped Darner sightings, Toronto has the highest daily chance: under 5%. Next come Montreal (Canada, under 5%).
GBIF citizen-science records
It is estimated from how often the Black-Tipped Darner is recorded against all the insects logged in Toronto (19 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.
