The Antrozoinae are a group of bats from the smooth-nosed family (Vespertilionidae). This group includes two species from North and Central America , Antrozous pallidus and Bauerus dubiaquercus . The systematic position of this group is controversial; sometimes it is raised to the rank of a separate family as the Antrozoidae.

description

Characteristic for these bats are the large, pointed ears and the trunk-like snout. The skull is relatively large and the teeth are strikingly strong. The color of the fur varies from yellowish white to dark brown. These animals reach a head trunk length of 57 to 75 millimeters and a weight of 13 to 28 grams.

The species

  • The desert bat ( Antrozous pallidus ) is distributed from southern Canada to Central America and is also found in Cuba . It is characterized by a light fur that is yellowish to light brown on the top and white on the underside. It lives mostly in mountainous terrain, both in forests and in dry desert areas. These animals live in groups of 20 to 100 animals that communicate with one another using a series of sounds. They hibernate in the cooler regions of their range. The diet of Antrozous pallidus consists of insects, spiders and also small vertebrates such as lizards, which they pick up from the ground.
  • Little is known of the Van Gelder bat ( Bauerus dubiaquercus ). The species is darker in color and somewhat smaller than Antrozous pallidus . Its distribution area extends from central Mexico to Costa Rica , where it mainly lives in tropical rainforests. It feeds on insects. The IUCN lists this species as endangered ( vulnerable ) due to the destruction of its habitat .
