Likely
About 40% of wildlife watchers report a White-Veined Arctic sighting in Wrangell-St. Elias National Park on a given day, based on 13 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 8th most-seen of the 27 insects we can rate there. Over three days the chance rises to about 70%, and over a week to over 90%, if each day is a fresh chance.
July
In that month about 50% of wildlife watchers report a White-Veined Arctic in Wrangell-St. Elias National Park on a given day, against under 5% in May and August, the lowest months. October to March have too few records to rate.
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.
Yes
Of the 4 parks where we can rate White-Veined Arctic sightings, Wrangell-St. Elias National Park has the highest daily chance: about 40%. Next come Kluane National Park (Canada, about 20%) and Denali National Park (United States, about 10%).

GBIF citizen-science records
It is estimated from how often the White-Veined Arctic is recorded against all the insects logged in Wrangell-St. Elias National Park (13 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.
