Eumops glaucinus
Wagner's bonneted bat

Found in South Florida, Cuba, Jamaica; from Central Mexico to Peru, Bolivia, Paraguay, Northern Argentina and Southern Brazil

A typical inhabitant of subtropical Forests but found in a variety of habitats in various geographic regions. Florida: subtropical forest; Cuba: primarily urban; Mexico: tropical forest; Costa rica: subtropical moist forest and urban; Venezuela: tropical moist forest; Argentina: deserts, scrublands, montane forest. E. glaucinus is frequently found in urban areas throughout its range.

E. glaucinus is medium sized compared to other species in its genus. Its color varies from black or brownish grey to chestnut. The venter is notably lighter. The snout is elongate with no noseleaf. The ears are wider than long and extend past the snout when brought forward. The tragus is 4-5mm and square across the top. The cranium is robust and longer than it is wide. A sagittal crest is present, along with a prominent occipitotemporal crest. Dental formula= 1/2 1/1 2/2 3/3 =30. The molars are succesively smaller in the toothrow with the third molar much smaller than the first two. The plagiopatagium extends to the heel. The uropatagium is moderately wide with the tail extending well beyond the margin. E. glaucinus has a pungent musky odor that has an unknown function.

Females lactate 5-6 weeks

Each colony of Eumops glaucinus consists of one male and several females. The colonies roost together and consistently roost shortly after sunrise. Members of this species become inactive in cooler climates but they are not known to hibernate.

These bats fly high and in straight lines to detect insects in the absence of clutter. They use echolocation to find insects at a distance of 3-5 m. They catch insects on the wing. Insects commonly eaten include: Coleoptera (beetles), Diptera (true flies), Hemiptera (true bugs), Lepidoptera (moths and butterflies) and Orthoptera (grasshoppers).

Eumops glaucinus potentially eats insects that are harmful to agriculture.

In Florida Eumops glaucinus has been place on the Florida Fish and Wildlife Conservation Commission's Endangered List. Pesticides are thought to be the reason for the species extinction from Miami FL.
