Data Sheet

IUCN Conservation Status: Endangered 

United States Conservation Status: n/a 

Diet: Insectivore 

The Antioquian sac-winged bat is strictly insectivorous, consuming primarily beetles, flies, and moths, which they catch in flight between 16 to 32 feet (5 to 10 meters) from the ground. 

Fun Fact: The members of the genus Saccopteryx are among the most communicative bat species. Males use a repertoire of visual, olfactory (thanks to their sac-shaped glands), and auditory displays to attract mates. Males can sing courtship songs to females, and pups learn to communicate through babbling and vocal imitation. 

Appearance: Saccopteryx antioquensis is a small bat with a body mass of 5 grams. It has a dark brown pelage without the characteristic two whitish longitudinal stripes along the dorsal side of the body present on the other species of the genus. The species has a well-developed open sac-shaped gland in its wings near the elbow. 

Habitat: The Antioquian sac-winged bat is an endemic species in Colombia. It has a very small distribution range, probably due to specific habitats and roost requirements, which include karstic formations and undisturbed wet forests.  

Conservation Concerns: This species is currently listed as ‘Endangered’ on the IUCN Red List since it was not reported for 20 years after being captured and described. It is only known from two localities, and during the last 15 years, surveys failed to record the species until December 2021. Additionally, little information about its status is known despite the limited extent of occurrence. However, known localities and similar habitats are subject to imminent threats by over 95 mining titles for large-scale limestone and marble extraction.
