Missouri’s occurrence databases hold just 4 records for this bat from 2000 to 2026, all iNaturalist observations that also appear in GBIF, one each from Laclede, Wayne, St. Louis, and Jefferson counties. A count that small fits a species that spends its life in dark roosts and is hard to document casually.
The refuges listed, Mingo, Big Oak Tree, and Swan Lake, sit near river-bottom forest and open water, the kind of habitat this bat favors for foraging over slow water at dusk. Records are sparse and scattered across the year rather than clustered in one season, consistent with a population researchers describe as thin and hard to track rather than one with a clear activity pulse.
NatureServe ranks it S2, Imperiled, in Missouri, well below its G3 global rank. White-nose syndrome, a cold-loving fungus first detected in 2006, has emptied entire hibernating colonies of this species across the country, and Missouri’s own numbers reflect that collapse.
