Evening bats carry no formal NatureServe rank in Mississippi, SNRB/SNRN unranked for both breeding and non-breeding populations, despite being one of the state’s better-documented bats with 94 records. Noxubee National Wildlife Refuge and Tombigbee National Forest each contribute a logged sighting, fitting the bottomland hardwood and pine habitat this colonial, tree- and building-roosting bat favors.

Records build steadily from spring into a June-July plateau, 40 of the year’s monthly-tallied sightings across those two months alone, tracking the maternity-colony season when females roost together to raise pups; activity falls off sharply by December as the bat becomes less detectable heading into winter.
