Possible
About 20% of wildlife watchers report a Moorland Clouded Yellow sighting in Wrangell-St. Elias National Park on a given day, based on 5 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 24th most-seen of the 27 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.
July
In that month about 30% of wildlife watchers report a Moorland Clouded Yellow in Wrangell-St. Elias National Park on a given day, against under 5% in May–June and September, the lowest months. October to March have too few records to rate.

GBIF citizen-science records
It is estimated from how often the Moorland Clouded Yellow is recorded against all the insects logged in Wrangell-St. Elias National Park (5 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.
