Florida Bonneted Bat (Eumops floridanus)

The Florida bonneted bat is Florida’s largest bat (approximate length: 3.3–4.3 in. = 83-109 mm) insectivorous bat.  The wingspan of this species of bat is generally 19-21 inches (482-533 mm) and weighs anywhere from 1.2-1.7 ounces.   Fur color ranges from dark gray to brownish-gray.  The tail extends beyond the short tail membrane.  The name bonneted bat was given to the species for its characteristically large broad ears that slant forward over the eyes like large bonnets.

This particular species of bat is colonial and tends to roost in cliff crevices, tree cavities, and buildings.  In 2003 a small colony was found roosting in a bat house in Fort Myers. 

The Florida bonneted bat is active year-round.  Females may have more than one reproductive cycle per year and give birth to a single pup. Pups are born during the summer from June through September.

The southeastern bat can be found in the southern portion of Florida, excluding the Florida Keys.

The southeastern bat is classified as Endangered by the Florida Fish and Wildlife Conservation Commission and is not listed federally.
