Under 5% of wildlife watchers report a Roadside Sallow sighting in Baltimore on a given day, based on 7 verified sightings from GBIF citizen-science data. It is the 486th most-seen of the 705 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.
October and December
In those months about 10% of wildlife watchers report a Roadside Sallow in Baltimore on a given day, against under 5% in January–September and November, the lowest months.
Only Baltimore, in our data

Same family: Noctuidae

GBIF citizen-science records
It is estimated from how often the Roadside Sallow is recorded against all the insects logged in Baltimore (7 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.
