Western Pipistrelle Bats (Pipistrellus hesperus) are the smallest North American bats. They often come out during the daytime and can be seen flying about in the afternoon catching flying insects. The flight pattern is light and buoyant, quickly changing direction to catch something tasty. When seen during the day, these tiny bats can be recognized by their light, tan fur and black bandit mask.
