Rare
Under 5% of wildlife watchers report a River Bluet sighting in Toronto on a given day, based on 37 verified sightings from GBIF citizen-science data. It is the 490th 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 River Bluet in Toronto on a given day, so our monthly data shows no clear season.
Between 3 and 6 pm
Across all the parks we cover, that three-hour window holds the most River Bluet sightings with a recorded time, and nearly all of them come between 6 am and 6 pm: it is a daytime animal.
Only Toronto, in our data
Toronto is the only city on Wallace's Line with enough records to rate River Bluet sightings: under 5% of wildlife watchers there report one on a given day.
GBIF citizen-science records
It is estimated from how often the River Bluet is recorded against all the insects logged in Toronto (37 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.
