Characteristics

This species is very similar in appearance to Myotis lucifugus (little brown bat), but can be distinguished due to its shorter, thicker, wolly fur. The fur on the back is a gray-brown to orange brown with the belly being more of a buff color. This species has long hairs on its toes that actually extend beyond the claws. This bat is between 77 and 97 mm in total length including the tail and weighs 5 to 8 g. In the northren part of the range (including VA), this speices may hibernate for as many as 7 months and in clusters of up to 100 individuals. Mating occurs in the fall, but the sprem is stored in the uterus of the female (delayed fertilization) through winter. Ovultion and fertilization takes place in the spring and typically two young are born in April or May. These bats form large nursery colonies.

Distribution

This range of this species in the US extends from extreme southeastern Virginia west to Texas and south to Florida. There are very few documentations of this species in Virginia. Those that do exist are along the Blackwater River near Zuni, VA. In the summer, this species uses caves as roosting sites where in the winter it typiclly prefers hollow trees, mines, caves, and buildings. The roosting site is always near a permanent body of water.

Foods

This species eats mainly insects, including mosquitos.
