Micronycteris microtis

Common Big-eared Bat

Order: Chiroptera
Family: Phyllostomidae


Conservation Status: Least Concern.

These very small bats are common where there are trees, even in orchards. They eat both fruit and insects, taking their food to a roost to eat it. Because they do this instead of eating it as they fly, and because they eat the body and drop the wings and legs of their prey, it is possible to identify a night’s feast. They are not picky eaters: one study of night roosts found the remains of insects from 13 different orders. They are also more flexible than some bats in their choice of roosts, finding shelter everywhere from the usual mines, caves, buildings, and hollow trees to large burrows made by other mammals and shallow holes on banks or among tree roots. About 4 to 6 bats are often found roosting together; they are more alert and quicker to fly away when disturbed than are some other species.

Range: Head and Body: 35-51 mm; Tail: 8-15 mm

Range: 4-9 g
