The fringe-lipped bat has wart-like bumps on its lips and muzzle, which give it its name.

[3] The fringe-lipped bat generally mates during the dry season in the tropics, usually from January to June.

Trachops cirrhosus is an opportunistic foliage-gleaning omnivore, eating mainly insects with some lizards, frogs (such as Hyalinobatrachium fleischmanni),[4][5] fruits, and seeds.

In rare cases this species has been idententified eating bats such as Furipterus horrens.

[3] Some frog species, such as Smilisca sila, have evolved methods of acoustic crypsis to confuse auditory predators like T. cirrhosus.

But because of its feeding habits, it is placed in a precarious position that puts it at a risk from human activity.
