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. Bats are important consumers for agricultural, forestry and human pest insects. It is estimated that bats in Wisconsin save farmers up to $658 million every year in the form of pest control services.

Bats in Wisconsin
Wisconsin has eight species of bats, all of which are insectivorous and use echolocation to navigate and capture prey. Four species are known as the cave bats and hibernate in caves and mines throughout the winter. The cave bats are all susceptible to the devastating bat disease white-nose syndrome. The other four are known as tree bats, and these bats migrate south to warmer climates during winter.
