Rare
Under 5% of wildlife watchers report an Even-Lined Sallow sighting in Chicago on a given day, based on 12 verified sightings from GBIF citizen-science data. It is the 637th 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 an Even-Lined Sallow in Chicago on a given day, so our monthly data shows no clear season.
Only Chicago, in our data
Chicago is the only city on Wallace's Line with enough records to rate Even-Lined Sallow sightings: under 5% of wildlife watchers there report one on a given day.
Same family: Noctuidae
The closest relatives of the Even-Lined Sallow that you can see in Chicago (family Noctuidae, Cutworm Moths and Allies) are American Dagger (about 10%), Armyworm Moth (about 10%) and Corn Earworm Moth (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Even-Lined Sallow is recorded against all the insects logged in Chicago (12 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.
