In 3 days ~10%
Agrotis venerabilis, the dusky cutworm, is a moth of the family Noctuidae. The species was first described by Francis Walker in 1857. It is found from coast to coast from central Canada south to Mexico. The wingspan is about 37 mm. Adults are on wing from August to September in temperate climes within their range. They have a much wider season in the Neotropics, starting at least as early as March.
The larvae feed on Medicago sativa, Trifolium, Nicotiana tabacum, Viola, Stellaria media, Avena sativa and Zea mays. Wikipedia →

Rare
Under 5% of wildlife watchers report a Venerable Dart sighting in Chicago on a given day, based on 6 verified sightings from GBIF citizen-science data. It is the 814th most-seen of the 978 insects we can rate there. Over three days the chance rises to about 10%, if each day is a fresh chance.
Any time of year
In every month with enough records, under 5% of wildlife watchers report a Venerable Dart in Chicago on a given day, so our monthly data shows no clear season.
Between 6 and 9 am
Across all the parks we cover, that three-hour window holds the most Venerable Dart 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 6 cities where we can rate Venerable Dart sightings, Chicago ranks 6th at under 5%, level with the leaders once rounded. The best odds are in Edmonton (Canada, under 5%), Toronto (Canada, under 5%) and Montreal (Canada, under 5%).
GBIF citizen-science records
It is estimated from how often the Venerable Dart is recorded against all the insects logged in Chicago (6 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.
