sommerbee 的最愛

I found this yesterday while searching through a creek for a biology project in the Appalachian Mountains. The water was cold and it was hiding under a rock. The length was approximately 4.5 centimeters long.

Help needed with ID, I am without my references just now. Silver hair seems pretty distinctive, but I seem to remember some other bat species have this color too.

This bat was inside a house, and torpid, but it appeared to rouse when placed in the sunlight outside, and after about 10 minutes, flew away.
