Bats are some of the most unique and ecologically beneficial animals in the world. They are the only mammals to have evolved true flight and there are over 1,200 species found worldwide. Bats are not rodents. They are in fact more related to primates than to rodents and they are members of their own order, Chiroptera which means "hand-wing".

Bats eat fruit, pollen, insects and other invertebrates, frogs, fish and even blood. In North America, bats are the primary predators of night-flying insects, and use echolocation to navigate and capture prey.

Wisconsin has eight species of bats, all of which are insectivorous. Check out the Bat FAQ for more information about bats in Wisconsin.
