The evening bat is a species of vesper bat native to North America. They typically inhabit much of the midwestern and eastern regions of the United States.

They are a small-sized bat, which weighs approximately 7-15 grams, with forearms spanning from 34 to 38 mm in length. The tip of their dorsal hair is light gray, with a brown pelage.

These bats have robust jaws compared to other insectivorous bats.

The average lifespan is less than four years, which might explain the higher reproductive output when compared to other bats that live longer.
