Their wings are formed by a double layer of skin stretched over the arm and elongated fingers. The membrane also extends to the hind legs and, in most species, between the legs and connecting with the tail. These membranes are not only used for flying, but also as a scoop for capturing insects in flight. Bats see well enough for on-site selection of a roost spot and in certain interactions with other bats. But bats are nocturnal.
Bats get around by echolocation.
They emit ultrasonic sound waves, above the range of human hearing, which bounce off solid objects, including moving insect prey. The sound bounces or echoes back to their highly sensitive ears, and their brain interprets size and distance and location from what is heard. Bats' ability to function in total darkness makes them alien and mysterious to many of us. Bats do not have a special liking for women's hair. They might accidentally touch human hair while pursing small insect prey, or while maneuvering in a small cave or room, but they have no special liking.
