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 →

Rare
Under 5% of wildlife watchers report a Florida Fern Moth sighting in Miami on a given day, based on 41 verified sightings from GBIF citizen-science data. It is the 228th most-seen of the 826 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.
June
In that month about 10% of wildlife watchers report a Florida Fern Moth in Miami on a given day, against under 5% in July to May, the lowest months. That is one of Miami's wettest months, with about 190 mm of rain against 45 mm in January.
Between 9 pm and midnight
Across all the parks we cover, that three-hour window holds the most Florida Fern Moth sightings with a recorded time, and about 8 in 10 of them come between 6 pm and 6 am: it is mostly seen at night.
Yes
Of the 9 cities where we can rate Florida Fern Moth sightings, Miami has the highest daily chance: under 5%. Next come Philadelphia (United States, under 5%) and Austin (United States, under 5%).
GBIF citizen-science records
It is estimated from how often the Florida Fern Moth is recorded against all the insects logged in Miami (41 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.
