Nycticeius humeralis, commonly known as the evening bat, inhabits deciduous forests and wooded areas across the southeastern United States. This small bat, with its dark brown fur and rounded ears, is known for its agile flight and nocturnal insect-hunting prowess. It roosts in tree cavities or human structures, playing a crucial role in pest control.

Nycticeius humeralis, commonly known as the evening bat, is native to North America. Its geographical distribution includes the eastern and central United States, ranging from as far north as southern Ontario in Canada, down to the Gulf Coast states in the U.S., and westward to eastern New Mexico. It is also found in parts of Mexico, particularly in the northeastern regions.

The evening bat typically inhabits warm, temperate regions. It is commonly found in deciduous and mixed forests, agricultural areas, and urban environments that offer suitable roosting sites. The species prefers areas with abundant tree cover, as they often roost in tree cavities or under loose bark. During the summer months, they may also be found in buildings or bat houses.

Nycticeius humeralis is primarily an insectivorous bat, playing a crucial role in controlling insect populations. It feeds on a variety of flying insects, including beetles, moths, and mosquitoes. The bat is nocturnal, emerging at dusk to forage. It typically roosts in small colonies, and its flight pattern is characterized by swift, agile movements that enable it to capture prey in mid-air.
