Evening bats reach close to the western edge of their range in Kansas; most of the population sits well to the south and east, in warmer forested country from Texas to the Carolinas. That edge-of-range position likely explains why occurrence here stays thin: 63 GBIF records against just 7 from iNaturalist, a gap that fits a small, plain brown bat easily mistaken for other species on sight and picked up instead through acoustic surveys and net captures.
Records concentrate in June and again in August and September, months that likely track when bat surveys run rather than a real summer spike in numbers. Cheyenne Bottoms, Quivira National Wildlife Refuge, and nearby reservoirs offer the wooded edges and open water this species hunts over, roosting by day in tree cavities or building crevices close by. NatureServe calls it apparently secure in Kansas (S4B), a step below its global rank of secure (G5), fitting a population near the thin edge of a much broader range.
