The little brown bat carries no NatureServe state rank on file in Nebraska, SNR unranked, even though the species’ G3 global rank and IUCN Endangered status both reflect the devastating impact white-nose syndrome has had on this bat across most of its range since the disease began spreading. Nearly all of the state’s 34 records, 32 of them, come from GBIF rather than casual photographs.

August alone accounts for 17 of the year’s monthly-tallied sightings, exactly half the total, tracking the weeks when maternity colonies are still active and young bats are flying, before the record falls nearly silent heading into fall migration and hibernation.
