Data Sheet

Diet: Insectivore

  • Strictly insectivorous, they hunt small, flying insects, including flying ants.

Fun Fact:

  • Unlike most nocturnal bats, some populations of lesser sac-winged bats are commonly active in bright conditions. They readily hunt in broad daylight, and fly fearlessly on moonlit nights.

Appearance:

  • These bats are small and delicate, weighing only 3-6g. Their dark brown fur highlights two pale, wavy stripes that run down their back.

Habitat:

  • Lesser sac-winged bats inhabit lowland deciduous and evergreen forests. They typically roost in small groups of fewer than ten individuals, most often clinging to tree trunks, though they are also known to roost on buildings.

Conservation Concerns

Bat Conservation International Projects:

  • Cave Conservation in Brazil

    The goal of this work is to utilize legal protection measures and tax incentives to provide long-term protection for 70 important cave roosts, protecting up to 82 species of bats.
