Aglossa caprealis
In 3 days ~10% in a week ~20%
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 →

Rare
Under 5% of wildlife watchers report a Stored Grain Moth sighting in Chicago on a given day, based on 16 verified sightings from GBIF citizen-science data. It is the 486th most-seen of the 978 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
In every month with enough records, under 5% of wildlife watchers report a Stored Grain Moth in Chicago on a given day, so our monthly data shows no clear season.
12th of 14
Of the 14 cities where we can rate Stored Grain Moth sightings, Chicago ranks 12th at under 5%. The best odds are in Rotterdam [The Hague] (Netherlands, about 10%), Vienna (Austria, about 10%) and Amsterdam (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 Chicago (16 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.
