An exhibition model done by the Denton Brothers of Wellesley, Massachusetts was discovered in a consignment shop in Flagler Beach, Florida on September 12, 2013 by Brittany Durocher, a resident of that city. It was collected by the Denton Brothers in Virginia and named Catocala amatrix virginurus.
The wingspan is 75–95 mm. The moths flies from August to October depending on the location. The larvae feed on Populus deltoides, Populus grandidentata, Populus nigra, Populus tremuloides, and Salix nigra. Wikipedia →

GBIF citizen-science records
It is estimated from how often the Sweetheart Underwing is recorded against all the insects logged in Denver (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.
