Micronycteris megalotis is a bat species from the family of leaf lobes ( Phyllostomidae ) which is native to Central and South America. The Greek generic name Micronycteris means " little bat ", the Latin species name megalotis refers to the large ears.
Description
Micronycteris megalotis is a small bat with large ears and a short pointed nose leaf, which is typical of the family of the sheet tabs. The coat is brown, with the base of about 10 mm long hair is white. The thumb is long and embedded halfway into the flight skin. The wings themselves are relatively short and wide, which makes this type into a flexible flyer. The legs are long and slender with a relatively long Kalkar, which supports the clamping of the tail wing membrane. The tail is short and extends only to the tip of the tail wing membrane. The total length of Micronycteris megalotis is 55-65 mm, the forearm length 32-38 mm and weight of 3.4 to 9.1 g 's ears Micronycteris megalotis, as with its sister species M. hirsuta and M. minuta over a narrow band connected. Micronycteris Megalancistrus is smaller than M. hirsuta (forearm length < 38 mm as compared to > 40 mm). M. minuta, in contrast to Micronycteris megalotis a white belly, the Kalkar is shorter than the foot and the tape between the ears has a deep notch. M. schmidtorum also has a notched belt between the ears and a white belly. The belly of Micronycteris megalotis is brown, the Kalkar longer than the foot and the tape between the ears has only a slight notch. Other species of the genus Micronycteris do not have a band between the ears and should not be confused with Micronycteris megalotis.
Way of life
Micronycteris megalotis is widespread and occurs in different habitats. The style is like most bats nocturnal and feeds on insects and other arthropods. It is rarely managed to get flying prey, but the arthropods collected from the leaf surface. It is known that Micronycteris megalotis may take even poisonous butterflies of the genus Parides from the family of Ritterfalter to himself. In Costa Rica, the food is the end of the rainy season and 70% during the dry season to 30% of beetles. Butterflies represent up to 40 % of the diet. According to reports Micronycteris megalotis occasionally eats fruits of ant trees ( Cecropia ), figs, bananas, Kirschmyrten ( Eugenia ), guava ( Psidium guajava ) and Solanaceae Solanum paniculatum like. During the day Micronycteris megalotis depends in hollow trees and logs, small caves and crevices, in abandoned buildings, under bridges and in tunnels. The hanging place they can be mixed with other bat species such as Anoura caudifer, the glasses leaf-nosed ( Carollia perspiciallata ), Carollia subrufa, Chiroderma trinitatum, the commons vampire ( Desmodus rotundus ), the white-winged vampire ( Diaemus youngi ) Glossophaga longirostris, Glossophaga soricina, Micronycteris minuta, Myotis nigricans, Natalus tumidirostris, Peropteryx kappleri, the Great Lanz nose ( Phyllostomus hastatus ), Pteronotus parnellii, the great sac-winged bat ( Saccopteryx bilineata ) and Frans lip bat ( Trachops cirrhosus ) share. Most animals are associated with up to 25 other dogs in a group.
Distribution and habitat
Micronycteris megalotis comes from Colombia to Brazil and northern Argentina before. The IUCN estimates the way thanks to their wide distribution and occurrence in protected areas as an unthreatened.
