Evening bats carry a NatureServe S5 secure rank in Louisiana, and the record leans overwhelmingly on GBIF specimen data, 346 of the state’s 363 records, since colonial bat surveys, not casual photographs, document most of what’s known about this species here.

June alone accounts for 108 of the 363 records, nearly a third of the entire year’s total, an extraordinary spike that tracks the maternity-colony season when females roost together in large numbers and survey teams count pups and adults at known roost sites; the smaller secondary bumps in April and October likely mark spring arrival and fall dispersal.
