Eastern Red Bat

Lasiurus borealis


Phylum: Chordata
Subphylum: Vertebrata
Class: Mammalia
Order: Chiroptera
Family: Vespertilionidae


The Red Bat varies from brick to rusty red The Red Bat is 10.8 - 12.5 cm (4.3 - 4.9 in) in total length. These bats have thickly furred tail membranes.

Life Cycle

Breeding occurs in autumn, and young are born the following spring. The Red Bat generally has four, more than any other bat in North America. Young are able to fly within 3 to 4 weeks. As with all bats the females carry the young only to move them to another roost. Females roost singly in both species and do not gather with other pregnant females to form a "maternity colony."

Natural History

This species spend their days hanging under the protective cover of tree leaves and clumps of Spanish Moss. The area directly beneath the roost must be unobstructed to allow the bats an easy drop at the beginning of their flight. Roosts are usually near a forest edge or body of water. The Red Bat typically roosts at heights of 1.5 - 6.1 m (5 - 20 ft). The Red Bat feeds on smaller beetles and moths. Various hawks and owls, Blue Jays, and Rat Snakes are known to prey on these bats.


This species is found throughout Georgia and has extensive ranges throughout North America. This species is migratory.

Conservation Status

This species is not considered to be threatened at this time.
