As night descends on Crokscrew, many animals are settling in for the night; however, others are just beginning to stir. One group of nocturnal animals that call Corkscrew home is bats. These often feared and misunderstood creatures are man's best natural pest controller of nocturnal insects. Corkscrew is home to at least 5 species of bat, including the evening bat (Nycticeius humeralis). This small bat is a mere 1.9-2.6 inches from nose to end and has a wingspan of 10-11 inches. True forest bats, they are at home zipping through Corkscrew's pine flatwoods and cypress swamps on the hunt for small nocturnal insects including beetles, flies, mosquitoes, moths, flying ants, and other insects. They use crevices and cavities of dead trees and loose bark to roost; they will also use bridges and bat houses. Colony sizes range from just a few to around 70 individuals. The evenig bat is one of the more abundant species of Florida, although they aren't found in the Keys. They are common throughout their range which covers the southeastern United States. The farther north in their range one travels the less common they become though.
