Little brown bats do us a big favor. They eat huge numbers of insects! That helps limit the spread of diseases and the damage that insects do to farm crops. But in recent years, large populations of little brown bats have been dying off each winter. Is a virus killing them? Could climate change or pesticides be the cause? Or is it something else? Follow a team of dedicated scientists working to save the little brown bats in this real-life science mystery.
