Hypena deceptalis
In 3 days ~10% in a week ~20%
Hypena deceptalis, the deceptive hypena or deceptive bomolocha moth, is a moth of the family Erebidae. The species was first described by Francis Walker in 1859. It is found in North America from Manitoba to Quebec, south to Florida and Texas. It is absent from much of Gulf Coastal Plain though.
The wingspan is 28–35 mm. The moth flies from April to August. There are two generations per year. The larvae feed on Tilia americana, but the species is also found outside of the range of Tilia americana, so there must be at least one other host. Wikipedia →

Rare
Under 5% of wildlife watchers report a Deceptive Snout sighting in Chicago on a given day, based on 18 verified sightings from GBIF citizen-science data. It is the 560th 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 Deceptive Snout in Chicago on a given day, so our monthly data shows no clear season.
Between 8 and 11 pm
Across all the parks we cover, that three-hour window holds the most Deceptive Snout sightings with a recorded time, and about 6 in 10 of them come between 6 pm and 6 am: it is seen both by day and at night.
Only Chicago, in our data
Chicago is the only city on Wallace's Line with enough records to rate Deceptive Snout sightings: under 5% of wildlife watchers there report one on a given day.
GBIF citizen-science records
It is estimated from how often the Deceptive Snout is recorded against all the insects logged in Chicago (18 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.
