Evening bats carry a NatureServe S5 secure rank in Nebraska, and the record leans toward GBIF (25 records) over iNaturalist (8), suggesting specimen and acoustic survey data document this small colonial bat more consistently than casual sightings. Indian Cave State Park’s single logged sighting fits the wooded river-bottom habitat this species favors in eastern Nebraska.

July alone accounts for 10 of the year’s monthly-tallied sightings, well over a third of the total, tracking the maternity-colony season when females roost together to raise pups; the record shows nothing at all from October through March.
