Evening bats carry a NatureServe S4 apparently secure rank in Arkansas, and the record leans heavily toward GBIF (72 of 79 records), meaning colonial bat surveys, not casual photographs, document most of what’s known about this species here. Ouachita National Forest’s single logged sighting is the only named site in the record.

August alone accounts for 34 of the 79 records, well over 40 percent of the entire year’s total, tracking the maternity-colony season when survey teams count roosting females and pups; the record goes nearly silent in January and February.
