Aglossa caprealis
In 3 days ~20% in a week ~30%
Aglossa caprealis, the stored grain moth, is a moth species of the family Pyralidae. It is found globally, though its native range is presumably the western Palearctic or nearby regions, as in other Aglossa species. The wingspan is 23–27 mm. The moth flies from June to August, depending on the location.
The larvae feed on dry plant waste, grain (e.g. maize), hay, straw and decaying manure. Sometimes, they even eat animal carcasses, suet, lard, pork rinds and other fatty materials. Wikipedia →

With luck
About 10% of wildlife watchers report a Stored Grain Moth sighting in Vienna on a given day, based on 51 verified sightings from GBIF citizen-science data. It is the 295th most-seen of the 1406 insects we can rate there. Over three days the chance rises to about 20%, and over a week to about 30%, if each day is a fresh chance.
June to August
In those months about 10% of wildlife watchers report a Stored Grain Moth in Vienna on a given day, against under 5% in September to May, the lowest months. Those are among Vienna's wettest months, with about 90 mm of rain a month against 40 mm in February.
Among the best
Of the 14 cities where we can rate Stored Grain Moth sightings, Vienna ranks 2nd at about 10%, level with the leaders once rounded. The best odds are in Rotterdam [The Hague] (Netherlands, about 10%).
GBIF citizen-science records
It is estimated from how often the Stored Grain Moth is recorded against all the insects logged in Vienna (51 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.
