![]() Larger insects are often disabled with a quick bite and then carried to the ground or to a perch for eating. Bats use their mouths to scoop small insects out of the air. They usually feed in areas where insects swarm, such as over water and agricultural fields, in forest clearings and along forest edges, and around street lights.Īll northeastern bats eat insects and take their prey on the wing. When at rest, a bat folds its wings alongside its body to protect the delicate finger bones and wing membranes.īats live in a variety of habitats, including wetlands, fields, forests, cities, suburbs, and agricultural areas. The bat's finger bones are greatly elongated and serve a purpose similar to struts on an airplane wing, providing support and maneuverability during flight. The wings of a bat are actually thin membranes of skin that stretch between the fingers of the front leg and extend to the hind legs and tail. ![]() ![]() They belong to their own unique order of mammals, called Chiroptera, meaning "hand wing," which refers to how the finger bones of a bat support its wings. That is, they actually flap their wings to propel them in flight. Hollow trees, beneath tree bark, caves, minesĪlthough some mammals are able to glide, bats are the only mammals that truly fly. Colors range from the drab brown of the little brown bat to the striking frosted red coat of the red bat. (See table.) Northeastern bats range in size from the hoary bat (length 5.1 to 5.9 inches from nose to tail wingspan 14.6 to 16.4 inches weight 0.88 to 1.58 ounces) to the pipistrelle bat (length 2.9 to 3.5 inches wingspan 8.1 to 10.1 inches weight 0.14 to 0.25 ounces). Nine species of bats live at least part of the year in the northeastern United States, and two southern species reside infrequently in Pennsylvania. Because of their role in controlling insect numbers throughout the Northeast and elsewhere in the United States, the maintenance of wild bat populations is important for maintaining ecosystem health. The red, hoary, and silver-haired bats help to maintain forest health in the region by feeding on forest pests such as tent caterpillar moths. Research has shown that over the course of a summer, a colony of 150 big brown bats can eat 38,000 cucumber beetles, 16,000 June bugs, 19,000 stinkbugs, and 50,000 leafhoppers and can prevent the hatching of 18 million corn rootworms by devouring the adult beetles.īig brown bats eat many agricultural pests, such as June beetles. A colony of just 100 little brown bats, the most abundant species in the Northeast, may consume more than a quarter of a million mosquitoes and other small insects each night.īig brown bats, which live primarily in agricultural areas, feed on June bugs, cucumber beetles, green and brown stinkbugs, and leafhoppers. A single bat can consume as many as 500 insects in just one hour, or nearly 3,000 insects every night. As the only major predators of night flying insects, bats play an important role in controlling many insect pests. Benefits of Batsīats make good neighbors. It will also discuss the reality behind the most commonly held misconceptions surrounding these beneficial mammals. This publication will describe the important role that bats play in our environment and will explain what to do if you find yourself sharing living quarters with them. Others consider them to be friendly, cuddly animals that need only our love and understanding. Many people think of bats as vicious animals that carry diseases and get tangled in hair. ![]() A variety of myths and misconceptions surround these small, nocturnal, flying mammals. As we mostly discuss woodland species in this spotlight, let’s take a closer look at these four tree bats.No other mammals in the Northeast are as misunderstood as bats. Those found in Maryland include the Eastern red bat, the hoary bat, the silver-haired bat, and the evening bat. Tree bats, on the other hand, are more solitary and may migrate or spend the winter in tree cavities, under bark, or even under tree litter. They are generally divided into two groups: ”cave bats” and “tree bats.” The six species of cave bats found in Maryland are generally year-round residents and will spend the colder months hibernating in colonies in natural caves or in man-made tunnels. Maryland is home to ten different species of bats, all of which are listed by the state as Species of Greatest Conservation Need. Consequently, more people are interested in helping bats in general, and in learning more about individual species in particular. Their reputations have been somewhat improved over the recent decades as science has discovered more of the species’ value to the environment, and as publicity of their plight related to White-nose Syndrome has widened. Bats have had centuries of bad publicity as, at best, oddball creatures, and at worst, connected to legends of vampires.
