Over the last fifteen years bat populations have dropped by up to 98% in some areas mostly due to white-nose syndrome, a fatal fungal disease for bats. A few years ago, grandson Reed helped construct a bat house which was placed on the side of our barn. The bat house was a success with the bats and one evening this week I counted at least 35 bats exiting the bat house. This week I found this bat in the lower level of the barn, hanging upside down from a mortise in a large beam. The common, highly descriptive, name for this bat is "big brown bat" (Eptesicus fuscus).
Big brown bats typically eat agricultural pests, like cucumber beetles and stinkbugs. A small colony of 25 bats can eat a pound of insects every night. A link to my blog post on constructing a bat house.
