Kitti's Hog-Nosed Bat: Craseonycteridae

Hog-nosed bats are crepuscular (kri-PUS-kyuh-lur), meaning that they are active at dawn and dusk. These bats are most active in the evening. A few minutes after the sun sets they leave the cave and fly in a circular pattern above the cave entrance for about one minute before flying away. They then separate into small groups and head off to a foraging area, a place to search for food, which is usually relatively close, within 820 feet (250 meters) of the cave.

Hog-nosed bats eat for about thirty minutes then return to the cave for the night. They are active again during the hours before sunrise. In the early morning they feed and then return to the cave.

The bats roost (settle or rest) together in caves in small numbers of up to fifteen individuals. While they roost together, the bats appear to be independent. They roost alone instead of clustered together with others.

From the shape of their wings and stomach content it appears that they can hover to catch their prey. It is unclear exactly how the hog-nosed bat captures its food. It could snatch small insects off surrounding leaves, twigs, or other surfaces. It could hunt near the ground. Other observations conclude that these bats may catch insects on their wings while flying.

Little is known about the hog-nosed bat's mating habits. The species is thought to be polygamous (puh-LIH-guh-mus), meaning that they have more than one mate during the mating season. There is evidence to show that the bats have their young during the beginning of the summer's rainy season.
