Asian long-winged bats live in large limestone caves in dark, wet water, gathering in large groups of thousands or even tens of thousands of individuals on top of the cave walls. It has a hibernation habit. They feed on small flying insects, especially hymenoptera and diptera. Miniopterus schreibersii was once thought to be widely distributed in Eurasia, but recent molecular phylogenetic and morphological studies have shown that it includes several species. Moreover, the subspecies <M. s. fuliginosus> distributed in China was elevated to species <M. fuliginosus> (Tian et al.,2004; Li et al.,2015).
Almost all bats rest during the day and forage at night. Although they have wings, they look very much like birds. But they don't have feathers, and they don't lay eggs. They have the characteristics of mammals: the female gives birth to her young and nurses them with milk.
It has been included in the Chinese Red List of Biodiversity - Vertebrate volume, and the assessment level is near threatened NT.
