In 3 days ~50% in a week ~80%
Eriogaster arbusculae is a moth in the family Lasiocampidae first described by Christian Friedrich Freyer in 1849. It is found in parts of the Alps and mountainous areas of Fennoscandia. The wingspan for adults is 31–35 mm for males and 36–43 mm for females. There is one generation per year with adults on wing from April to July.
The larvae feed on the leaves of Vaccinium myrtillus, Vaccinium uliginosum, Betula, Salix and Alnus species. Wikipedia →

Possible
About 20% of wildlife watchers report an Eriogaster arbusculae sighting in Hohe Tauern National Park on a given day, based on 19 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 29th 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 and August
In those months about 30% of wildlife watchers report an Eriogaster arbusculae in Hohe Tauern National Park on a given day, against under 5% in February–May and September, the lowest months. December has too few records to rate.
Between 11 am and 2 pm
Across all the parks we cover, that three-hour window holds the most Eriogaster arbusculae sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Only Hohe Tauern National Park, in our data
Hohe Tauern National Park is the only park on Wallace's Line with enough records to rate Eriogaster arbusculae sightings: about 20% of wildlife watchers there report one on a given day.
GBIF citizen-science records
It is estimated from how often the Eriogaster arbusculae is recorded against all the insects logged in Hohe Tauern National Park (19 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.
