Western Little Brown Myotis in Florida, by the numbers

Rare in Florida 104th most recorded of 116 mammals logged in Florida

Records from 2000–2026.

Seasonality

No dated Florida records from 2000 to 2026.

Florida has no dated records of the western little brown myotis from 2000 to 2026, from either iNaturalist or GBIF. NatureServe hasn’t assigned the state a numeric rank for this species, though it’s treated as native to Florida’s mapped range.

With nothing recorded in that window, there’s no pattern of place or season to describe. A small, hard-to-survey bat can go unrecorded for years, so the gap says more about how rarely anyone documents it in Florida than about where it lives.

Occurrence data from GBIF.
