Possible
About 20% of wildlife watchers report a Moorland Clouded Yellow sighting in Hohe Tauern National Park on a given day, based on 13 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 48th most-seen of the 165 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 Hohe Tauern National Park on a given day, against under 5% in February–May and September–October, the lowest months. December has too few records to rate.
Between 10 am and 1 pm
Across all the parks we cover, that three-hour window holds the most Moorland Clouded Yellow sightings with a recorded time, and nearly all of them come between 6 am and 6 pm: it is a daytime animal.
Among the best
Of the 5 parks where we can rate Moorland Clouded Yellow sightings, Hohe Tauern National Park ranks 2nd at about 20%, level with the leaders once rounded. The best odds are in Wrangell-St. Elias National Park (United States, about 20%).
GBIF citizen-science records
It is estimated from how often the Moorland Clouded Yellow is recorded against all the insects logged in Hohe Tauern 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.
