occurs from Costa Rica to Peru and Brazil and onto Trinidad (UNEP-WCMC Online Database, 2001).
is found in caves. They have also been known to live near or around streams and other moist areas deep in the forests. They have been found hanging in clusters in hollowed out logs (Nowak, 1994).
Length usually is from 33-40 mm, tail length around 24-36 mm, and forearm length from 30-40 mm (Nowak, 1994). Average specimens weigh about 3 grams (Nowak, 1994). The fur on the head is fairly long and thick, covering all the head as far as the mouth, almost concealing the mouth (Nowak, 1994). The tail is short, with both surfaces of the uropatagium haired (Nowak, 1994). The coloration is brownish gray, dark gray, or slaty blue above and usually somewhat lighter below (Nowak, 1994). Specimens of(along with those of the related genus Amorphochilus) are easily distinguished by their reduced thumbs, which are included in the wing membrane that runs to the base of the small, funtionless claw (Nowak, 1994). The ears are seperate and funnel-shaped, while the snout is piglike (Nowak, 1994). Females are usually significantly larger than males. Their dental formula is 2/3, 1/1, 2/3, 3/3=36 (Nowak, 1994).
After being born the young position themselves head up on the mother's body (Nowak, 1994). This is in response to the unusual abdominal location of the mammae combined with the fact that the mothers hang in the usual head down position (Nowak, 1994).
live in colonies from about 100 to 150, and sometimes upwards of 300, individuals (Nowak 1994). In these colonies they sometimes divide into separate groups of 4-30, while some colonies roost with each individuals separating from one another (Nowak 1994). They leave their caves to forage when it is dark. They use echolocation calls that are short, low intensity, and high frequency (Nowak 1994).
Lepidoptera) (Nowak, 1994). They usually look for prey at heights of 1-5 meters above the forest floor (Nowak, 1994).are insectivorous. Evidence from fecal samples suggests that they mainly prey on butterflys and moths (

young are born in a relatively underdeveloped state; they are unable to feed or care for themselves or locomote independently for a period of time after birth/hatching. In birds, naked and helpless after hatching.
having body symmetry such that the animal can be divided in one plane into two mirror-image halves. Animals with bilateral symmetry have dorsal and ventral sides, as well as anterior and posterior ends. Synapomorphy of the Bilateria.
an animal that mainly eats meat

used loosely to describe any group of organisms living together or in close proximity to each other - for example nesting shorebirds that live in large colonies. More specifically refers to a group of organisms in which members act as specialized subunits (a continuous, modular society) - as in clonal organisms.
animals that use metabolically generated heat to regulate body temperature independently of ambient temperature. Endothermy is a synapomorphy of the Mammalia, although it may have arisen in a (now extinct) synapsid ancestor; the fossil record does not distinguish these possibilities. Convergent in birds.
An animal that eats mainly insects or spiders.

rainforests, both temperate and tropical, are dominated by trees often forming a closed canopy with little light reaching the ground. Epiphytes and climbing plants are also abundant. Precipitation is typically not limiting, but may be somewhat seasonal.
