Summary ²

The evening bat (Nycticeius humeralis) is a species of bat in the vesper bat family, Vespertilionidae, that is native to North America. It is a small bat (7–15 grams) found throughout much of the midwestern and eastern United States as well as northeastern Mexico. In many areas (especially the Gulf Coast states) they are very common, but they may be declining in some states. During the summer, they commonly roost in tree cavities but is also found occasionally in man-made structures. Colonies are generally small in trees, but groups can reach nearly 1,000 individuals, especially in buildings. Evening bats feed heavily on beetles (Coleoptera), but they also eat moths (Lepidoptera) and to a lesser extent flies (Diptera) and other insects.
