Rare
Under 5% of wildlife watchers report a Nut-Tree Tussock sighting in Vienna on a given day, based on 19 verified sightings from GBIF citizen-science data. It is the 643rd most-seen of the 1406 insects we can rate there. Over three days the chance rises to about 10%, and over a week to about 20%, if each day is a fresh chance.
Any time of year

GBIF citizen-science records
It is estimated from how often the Nut-Tree Tussock is recorded against all the insects logged in Vienna (19 verified sightings), 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.
