Any time of year
In every month with enough records, under 5% of wildlife watchers report a Giant Crane Fly in Toronto on a given day, so our monthly data shows no clear season.
Between 10 am and 1 pm
Across all the parks we cover, that three-hour window holds the most Giant Crane Fly sightings with a recorded time, and about 7 in 10 of them come between 6 am and 6 pm: it is a daytime animal.

GBIF citizen-science records
It is estimated from how often the Giant Crane Fly is recorded against all the insects logged in Toronto (10 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.
