Eumops patagonicus

Eumops patagonicus

Patagonian Dwarf-bonneted Bat

The Patagonian Dwarf bonneted bat is aptly named due to its very large fleshy ears that meet in the middle.  It is the smallest of the genus Eumops which is in the Molossidae family.  It has a long free tail and hairy large feet.  Colouring is grey/brown with a paler underbody.  The weight can be from 12-18 grams.

It is found in South America (Argentina, Bolivia and Paraguay), and is a fast flying insectivore with long narrow wings which enable it to fly long distances to hunt.

It is common to find them in houses and other buildings but they also roost in trees.  Their echolocation signal is low enough to be audible to some humans which is typical for this family.

We have caught this species many times around the reserve whilst mist netting for bats and we often pick up its echolocation frequency on our detectors.  It is the most common local bat.
