Rare
Under 5% of wildlife watchers report a White-Striped Black sighting in Montreal on a given day, based on 47 verified sightings from GBIF citizen-science data. It is the 207th 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 30%, if each day is a fresh chance.
May to August
In those months about 10% of wildlife watchers report a White-Striped Black in Montreal on a given day, against under 5% in September to April, the lowest months.
Between noon and 3 pm
Across all the parks we cover, that three-hour window holds the most White-Striped Black sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Yes
Of the 7 cities where we can rate White-Striped Black sightings, Montreal has the highest daily chance: under 5%. Next come Toronto (Canada, under 5%) and Minneapolis [Saint Paul] (United States, under 5%).
Same family: Geometridae

GBIF citizen-science records
It is estimated from how often the White-Striped Black is recorded against all the insects logged in Montreal (47 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.
