THE PIPISTRELLE. (Vespertilio Pipistrellus.)

This little creature, which is only an inch and a half in length, appears to be the commonest of all Bats in most parts of Britain. It usually resides in cracks and cavities in old brick walls and in sheltered corners about houses, and at the approach of evening quits its retreat, and flies about capturing the gnats and other small twilight-loving insects on which it feeds.
