Bumblebee bats eat insects such as beetles and spiders, and they are actually known as the hog-nosed bat. The term "bumblebee bat" is a nickname for the bat due to its small stature that is similar to the size of a large bumblebee.
The hog-nosed bat, or bumblebee bat, weighs approximately 2 grams. It is 29 to 33 mm long, with a wingspan that is 22 to 26 mm long. The hog-nosed bat lives within caves in groups as small as 10 and as large as 500. The bats prefer limestone caves that are near heavily forested areas because they do not like to leave their caves for long to find food. They also do not like to travel far away from their caves.
The hog-nosed bat is nearing extinction with only 2,000 bats left in the wild in Thailand. The species has officially been listed as "endangered" by the International Union for Conservation of Nature. Initially, the species was nearing extinction because collectors of exotic animals were eager to obtain the hog-nosed bat as a pet for their collection. However, once laws were enacted to protect the bats from this state, it was the habitat destruction that pushed the bats onward towards extinction. In Thailand, there is also a ceremonial burning of the forested regions surrounding caves. This has made it difficult for the bats to find suitable homes to grow and thrive.
