Florida holds just 12 records of the western little brown myotis, all from GBIF with none from iNaturalist. NatureServe hasn’t assigned the state a numeric rank for this species, though it’s treated as native to Florida’s mapped range.

Records split evenly between May and August, four each, with nothing recorded in any other month. With so few detections overall, that even split looks more like the pattern of a hard-to-survey bat than a real seasonal peak.
