There are many varieties of bat & they all eat lots of bugs. This is very likely the so-called Midwestern Grey Bat, an endangered species, because it is being out-competed in its environment by other very similar varieties of bats that share the same habitat. The framers of the Endangered Species Act apparently forgot that evolution continues and isolated sub species of various critters go out of existence all the time, while new ones replace them.
Not long ago the Interior Departmment virtually shutdown the logging industry in the Pacific Northwest to protect the Spotted owl, which was being out competed in the region by the Brown owl. A large industry was shutdown, but the Brown owl went on to replace the Spotted owl anyway.
