Rhodoecia aurantiago, the orange sallow moth or aureolaria seed borer, is a species of moth of the family Noctuidae. It has a scattered distribution from southern Maine and the hills around Boston, Massachusetts, west across southern Ontario to south-western Wisconsin and Missouri, south into Florida and Texas. It is listed as threatened in the US state of Connecticut.
The wingspan is about 30 mm. Adults are on wing from July into September in the north. In the south adults are on wing mostly in September in Texas and North Carolina, and from sometime in September through October in Florida.

Rare
Under 5% of wildlife watchers report an Orange Sallow sighting in Boston on a given day, based on 6 verified sightings from GBIF citizen-science data. It is the 967th most-seen of the 1200 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 Orange Sallow in Boston on a given day, so our monthly data shows no clear season.
Only Boston, in our data
Boston is the only city on Wallace's Line with enough records to rate Orange Sallow sightings: under 5% of wildlife watchers there report one on a given day.
Same family: Noctuidae
The closest relatives of the Orange Sallow that you can see in Boston (family Noctuidae, Cutworm Moths and Allies) are Large Yellow Underwing (about 10%), Armyworm Moth (about 10%) and American Copper Underwing (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Orange Sallow is recorded against all the insects logged in Boston (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.
