Rare
Under 5% of wildlife watchers report a California Tortoiseshell sighting in Toronto on a given day, based on 5 verified sightings from GBIF citizen-science data. It is the 1544th most-seen of the 1689 insects we can rate there. Over three days the chance rises to about 10%, if each day is a fresh chance.
Any time of year
In every month with enough records, under 5% of wildlife watchers report a California Tortoiseshell in Toronto on a given day, so our monthly data shows no clear season.
Between 11 am and 2 pm
Across all the parks we cover, that three-hour window holds the most California Tortoiseshell sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
8th of 8
Of the 8 cities where we can rate California Tortoiseshell sightings, Toronto ranks 8th at under 5%. The best odds are in Salt Lake City (United States, about 10%), Portland (United States, about 10%) and San Francisco (United States, about 10%).
GBIF citizen-science records
It is estimated from how often the California Tortoiseshell is recorded against all the insects logged in Toronto (5 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.
