Rare
Under 5% of wildlife watchers report a White-Horned Horntail sighting in Montreal on a given day, based on 8 verified sightings from GBIF citizen-science data. It is the 634th most-seen of the 926 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 White-Horned Horntail in Montreal on a given day, so our monthly data shows no clear season.
Between noon and 3 pm
Across all the parks we cover, that three-hour window holds the most White-Horned Horntail sightings with a recorded time, and about 8 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Among the best
Of the 3 cities where we can rate White-Horned Horntail sightings, Montreal ranks 2nd at under 5%, level with the leaders once rounded. The best odds are in Vancouver (Canada, under 5%).
GBIF citizen-science records
It is estimated from how often the White-Horned Horntail is recorded against all the insects logged in Montreal (8 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.
