Rare
Under 5% of wildlife watchers report an Ochre Dagger sighting in Toronto on a given day, based on 9 verified sightings from GBIF citizen-science data. It is the 1135th 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 an Ochre Dagger in Toronto on a given day, so our monthly data shows no clear season.
Between 8 and 11 am
Across all the parks we cover, that three-hour window holds the most Ochre Dagger sightings with a recorded time, and about half of them come between 6 am and 6 pm: it is seen both by day and at night.
Only Toronto, in our data
Toronto is the only city on Wallace's Line with enough records to rate Ochre Dagger sightings: under 5% of wildlife watchers there report one on a given day.
GBIF citizen-science records
It is estimated from how often the Ochre Dagger is recorded against all the insects logged in Toronto (9 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.
