What is a group of bats called?

Bats are mammals of the order Chiroptera, which is the second largest order of mammals after rodents. They are commonly divided into two suborders: the Megachiroptera (large fruit bats or flying foxes) and the Microchiroptera (small insect-eating bats).

One group of bats within the Microchiroptera suborder is called the Vespertilionidae, or vesper bats. This family is one of the most diverse and widespread groups of bats, with about 440 species found around the world.

Vesper bats are typically small to medium-sized bats with fairly simple facial features and a wide range of diet preferences, including insects, fruit, nectar, and blood. They are known for their agile flight and echolocation abilities, which they use to navigate and locate prey in the dark.

Some common species of vesper bats include the brown long-eared bat, the common pipistrelle, and the big brown bat. These bats play important roles in ecosystems as both predators of insects and pollinators of plants.

Overall, vesper bats are a diverse and ecologically important group of bats that are found in a variety of habitats around the world.
