Pennsylvania is an enormous state containing different types of wildlife. The Appalachian Mountains run from the southeast to the northwest of this state; therefore, you can imagine the amount of flying creatures in this state. The largest portion of Pennsylvania’s income comes from its farms. There is a mixture of flying animals and insects that help control pests around farmland; however, there is one particular flying insect that is a big threat. This article will list the most common flying creatures seen throughout this large, populous state.

1. Northern Flying squirrel

The Northern Flying squirrel is an endangered species protected by the Game and Wildlife Code. There are two types of this species in Pennsylvania, the northern and southern flying squirrel. The northern squirrel lives in the northern conifer forests whereas, the southern live all over the state. The flying squirrel can travel about 65 feet in the air when traveling. They have skin flaps between their wrists and ankles to fly and a flat tail to help them steer in the sky.

2. Bats

There are nine different species of bats in Pennsylvania. The Northern Long-eared and Indiana bats are the two species out of nine that are endangered. Bats are in areas of the state containing woods, caves, tunnels, and mines. When near a bats home, you may hear a high-pitch screech. This noise is called echolocation, which aids them in determining how large objects are around them.

3. Eurasian Goshawk

The Eurasian Goshawk can soar the skies in the northern tier of Pennsylvania. They nest in mixed forests and high elevations of the state. This hawk is an ambush hunter, meaning they wait quietly for their prey and then attack at high speeds. The size of the goshawk is similar to the forest raptor because of its short, round wings, and long tail.

4. Red-tailed Hawk

The Red-tailed hawks sit on tall perches near highways in search of their next prey. This hawk feeds on lizards, rabbits, rodents, and other small animals. They nest in dense hardwood forests of Pennsylvania to avoid any potential threats or predators. The female hawk can lay between 1 to 5 white eggs with brown spots.

In 1980, there were only three pairs of Bald eagles in Pennsylvania. By 2006, there were about 100 nesting pairs found, so you can understand why these creatures are protected. Eagles have a wingspan of 7 feet and can weigh up to 14 pounds. The Moraine State Park near Petersville is a great spot to observe these creatures soar through the sky between summer and fall.

11. Dobsonfly

The Dobsonfly is a grayish-brown flying insect with large pinchers. This large fly is active between late spring and mid-summer months. This pesky fly is attracted to porch lights, so do not be surprised if you see this creature hanging around. Although the male Dobsonfly looks intimidating, it is the females you should be cautious of. The female fly can bite down hard enough on human skin that it draws blood.

The Spotted Lanternfly is native to Asia and was discovered in Berks County, Pennsylvania in 2014. This large flying insect is notorious for causing severe damage to crops and agriculture. This insect is in 51 counties of Pennsylvania and the Department of Agriculture is trying to keep this creature from spreading all over the state. It is recommended that if this insect is seen outside of the quarantine zone, kill it and notify the proper authorities.

13. Bald-Faced Hornet

The Bald-Faced Horney is commonly found in Philadelphia, Pennsylvania. This hornet is part of the yellow jacket family and is extremely territorial. Female hornets will sting their victims repeatedly leaving red marks on the skin. The Bald-Face hornet builds its nests in shrubs, trees, and on sides of houses.

14. Wheelbug

The Wheelbug is commonly seen in the southwest parts of Pennsylvania. The Wheelbug will help rid pest insects in gardens and around forests. The bug has earned its name because of the crested-like wheel on its back. This insect is slow to defend, but when it does their bite is worse than the sting of a wasp. The bite will leave a localized numbness that can last for days.
