About 20% of wildlife watchers report a White-Veined Arctic sighting in Kluane National Park on a given day, based on 8 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 18th most-seen of the 39 insects we can rate there. Over three days the chance rises to about 50%, and over a week to about 80%, if each day is a fresh chance.
June and July
In those months about 30% of wildlife watchers report a White-Veined Arctic in Kluane National Park on a given day, against under 5% in April–May and August–September, the lowest months.

GBIF citizen-science records
It is estimated from how often the White-Veined Arctic is recorded against all the insects logged in Kluane National Park (8 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.
