Spiders (order Araneae) are air-breathing arthropods that have eight legs and chelicerae with fangs that inject venom. They are the largest order of arachnids and rank seventh in total species diversity among all other groups of organisms. Spiders are found worldwide on every continent except for Antarctica, and have become established in nearly every habitat with the exception of air and sea colonization. As of 2008, at least 43,678 spider species, and 109 families have been... less ↑

Damselflies (suborder Zygoptera) are insects in the order Odonata. Damselflies are similar to dragonflies, but the adults can be distinguished by the fact that the wings of most damselflies are held along, and parallel to, the body when at rest. Furthermore, the hindwing of the damselfly is essentially similar to the forewing, while the hindwing of the dragonfly broadens near the base. Damselflies are also usually smaller than dragonflies and weaker fliers in comparison, and their... less ↑

Orthoptera is an order of insects with paurometabolous or incomplete metamorphosis, including the grasshoppers, crickets, cave crickets, Jerusalem crickets, katydids, weta, lubber, Acrida, and locusts. Many insects in this order produce sound (known as a "stridulation") by rubbing their wings against each other or their legs, the wings or legs containing rows of corrugated bumps. The tympanum or ear is located in the front tibia in crickets, mole crickets, and katydids, and on the first abdominal... less ↑

Identification
The leopard frog can be identified by its markings, colors, and size. The background color of the frog varies from a bright green to a dark greenish brown or even just brown. There are rows of circular brown or black spots bordered with white or yellow lines down upper and side surfaces of the head as well as the body and appendages. This is different from other frogs that live in this region: pickerel frog. The other frog species have rectangular spots and have red-orange coloring rather than the green-brown of the leopard frog.

Niche
Energy Role
The leopard frog is a consumer because it eats other organisms to get its energy. The leopard frog eats almost anything that will fit into its mouth. Most commonly it will eat food such as, beetles, ants, flies, worms, smaller frogs (including its own species), and even birds and garter snakes. The leopard frog doesn’t just eat other animals, other animals eat leopard frogs. Animals such as, herons, raccoons, snakes, and owls. Leopard frogs are also brought to the kitchen. Some of us eat frog legs and they might just be a leopard frogs leg! Leopard frogs are important to us because we eat them to give us energy to get through the day.

Other Roles in the Ecosystem
In addition to being an important food source in their ecosystem, leopard frogs play some more important roles. For example, they keep insect populations in check.

Identification
The mink can be identified by its size and tracks. A mink is the size of a small cat but slender and their skull is flat and pointed. Male minks are a bit larger than female minks. Minks are dark brown with white spots on their chins and chests. On each foot they have five webbed toes. In their tracks their heels do not show.

Niche

Energy Role
Minks are consumers, because they eat other organisms to get their energy. A mink is a carnivore because it eats animals. The animals they like to eat are, muskrats, mice, rabbits, birds, and chipmunks. Minks are an important species in the ecosystem, they are prey for, wolves, coyote, bobcats, and even humans.

Other Roles in the Ecosystem
Mink are the main hunters of small animals all over their area. Humans are are a big predator to minks. Mink pelts have for awhile been chosen as one of the most deluxe furs on retail. Since the mid 1900s mink ranches were settled to help bring more steady pelt amount to the exchange.

Identification
A muskrat looks similar to a large rat. It has 4 toes on its front feet and 5 on its back. Their rat-like tail often leaves a visible track. The walking stride of a muskrat is an average of 11 inches. Usually scat is found on the water's edge.

Niche
The muskrat is a consumer because it eats other living organisms to get its energy. Muskrats eat a large variety of plants and animals including; cattails, sedges, rushes, water lilies, pondweeds, wild rice, pickerel weed, clover, willow, acorns, sweet flag, switchgrass, mussels, crayfish, frogs, snails, and fish. As well as eating many different things, many things eat them. Some of these animals include; raccoon, red fox, owls, hawks, american bald eagles, common snapping turtles, bullfrogs, largemouth bass, cats, dogs, and even sometimes people.

Other roles in the ecosystem
As well as being an important part of the food chain muskrats serve other roles in the ecosystem. Muskrats influence the composition of local plant communities. This is important because it keeps one plant from overpopulating and lets new plants grow.

Identification:
The beaver has a flat tail, is pretty large, and has webbed hind feet. You can tell if they are around by sign as well. For example, it drags its tail and covers the paw marks. Its scat’s large like a marshmallow and consists of woodchips. Scat is deposited in water.
