Florida has 35 records of Rafinesque’s big-eared bat, with 10 from iNaturalist and 32 from GBIF. NatureServe ranks it S1, critically imperiled in the state, even though it’s classified as native to Florida’s range.

August is the clear peak, with 11 records, more than double the next-highest month. January follows with four. Rafinesque’s big-eared bat roosts in hollow trees and old buildings, so that late-summer spike may reflect roost surveys rather than a true seasonal shift.
