Callopistria floridensis, the Florida fern moth or Florida fern caterpillar, is a moth of the family Noctuidae. It is found in North America (including Alabama, California, Florida, Georgia, Iowa, Louisiana, New Brunswick, New Mexico, North Carolina, Ohio, Oklahoma, Ontario, Pennsylvania, South Carolina, Tennessee and Texas), south through the Caribbean (including Cuba), Mexico and Central America (including Costa Rica) to Ecuador.
The wingspan is about 29 mm (1.1 in). Adults are on wing year round in Florida and the tropics. The larvae feed on various ferns, including Nephrolepis exaltata and Pteris vittata. It is an occasional pest in greenhouses. The larvae were recently discovered to have high levels of arsenic when feeding on P. vittata, and are the only known terrestrial animal to accumulate arsenic. Wikipedia →

GBIF citizen-science records
It is estimated from how often the Florida Fern Moth is recorded against all the insects logged in Everglades National Park (18 verified sightings from 2019 to 2026), 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.
