The cave myotis (Myotis velifer) is a species of vesper bat (Vespertilionidae) in the genus Myotis. It is larger than most other bats in the Myotis group, with a forearm of 37 to 44 millimetres (1.5 to 1.7 in). The bat is brown with short ears, and can be distinguished from other large Myotis by a bare patch of skin on its back.

The Cave myotis (Myotis velifer) is a medium-sized bat with brown or black fur on its back and paler fur on its underside. Its ears are short and pointed and its eyes are small. During the summer these bats can be found roosting in caves in groups of 2,000-5,000 individuals.

The cave Myotis prefers forested habitat across a range of elevations. This species roosts in caves, tunnels, buildings, and abandoned mines. Some cave Myotis have been observed migrating south for winter, while others hibernate near their summer habitat.

Hibernation caves have high humidity, often with standing or running water and little air movement. Hibernating cave myotis may form clusters. Uses temporary night roosts. Reproduction: Nursery colonies are in the hibernation cave or another cave. Occasionally other sites, such as bridges, are used. Males may be found in the maternity colony.

In Texas, Cave Myotis occupy the High Plains, Rolling Plans, Trans-Pecos, Edwards Plateau, and South Texas Plains during the summer. Bat-friendly gates can prevent human disturbance of roosting sites in caves and mines.

Cave myotis are aerial insectivores and feed on a wide variety of insects including moths, weevils, antlions, small beetles and flying ants. Because these bats congregate in large groups, they are very susceptible to human disturbance.
