Rare
Under 5% of wildlife watchers report a White-Veined Arctic sighting in Banff National Park on a given day, based on 7 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 89th most-seen of the 105 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.
July
In that month about 10% of wildlife watchers report a White-Veined Arctic in Banff National Park on a given day, against under 5% in August to June, the lowest months.
Between 1 and 4 pm
Across all the parks we cover, that three-hour window holds the most White-Veined Arctic sightings with a recorded time, and about 8 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
4th of 4
Of the 4 parks where we can rate White-Veined Arctic sightings, Banff National Park ranks 4th at under 5%. The best odds are in Wrangell-St. Elias National Park (United States, about 40%), Kluane National Park (Canada, about 20%) and Denali National Park (United States, about 10%).
Same genus: Oeneis
The closest relatives of the White-Veined Arctic that you can see in Banff National Park (genus Oeneis, Arctics) are Macoun's Arctic (about 10%) and Chryxus Arctic (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the White-Veined Arctic is recorded against all the insects logged in Banff National Park (7 verified sightings from 2019 to 2026), 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.
