Little brown bats, Myotis lucifugus, are abundant in southern Alaska, Canada, across the United States from the Pacific to Atlantic coasts, and the higher elevation forested regions of Mexico.

Myotis lucifugus is an efficient insect predator, especially when insects are in patches and at close range. These bats typically eat half of their body weight per night.

Mating occurs in two phases: active and passive. During the active phase, both partners are awake and alert. In the passive phase, active males mate with torpid individuals of both sexes; passive phase mating is approximately 35% same-sex.

Mating is random and promiscuous. Females in active phase usually mate with more than one male. In both active and passive phase matings, males mate with multiple females.

    This is great! Bats are amazing. Did you hear the one about their giant heart-shaped penises?

    The bats’ penises are around seven times longer than their partners’ vaginas and have a “heart-shaped” head that is seven times wider than the vaginal opening. Both the penises’ size and shape would make penetration post-erection impossible. The researchers show that, rather than functioning as a penetrative organ, the bats use their oversized penises like an extra arm to push the female’s tail sheath out of the way so that they can engage in contact mating. This behavior resembles “cloacal kissing” in birds.
