Great Blue Skimmer
The great blue skimmer is a multicolored dragonfly. It may be blue, black, yellow, green, white or brown in color. The iridescent wings of this bug can be spotted. Larvae are developed in still waters, though the hatched skimmer is not primarily a water bug. This insect is also called the king skimmer.
Caddisfly
Caddisflies are brown, yellow or green in color with wings that can vary from tan to gray. This insect is moth-like in appearance and has a set of long antennae. Larvae develop in moving waters such as rivers or streams and require vegetation for a food source and shelter.
Whirligig Beetle
The whirligig beetle swims in a circular motion using its flat legs as paddles. This bug has two sets of eyes so it can search for predators above and below the water at the same time. Larvae and adult beetles reside in water including lakes and rivers. This insect mainly stays on the surface of the water and eats dead animals.
Damselflies
Damselflies are brown, black, green, red or blue in color. The damselfly looks similar to a dragonfly but has a more slender body and holds its wings vertically to its body instead of horizontally. The adult damselfly eats flying insects such as mosquitoes.
Mayflies
The mayfly is brown with feather or plate-like gills on each side of its body. The adult mayfly does not consume food and dies anywhere from a few hours to a few weeks after reaching adulthood. The larva has two or three tails coming out of its abdomen, giving it a distinct appearance. Mayflies reside in lakes, rivers, streams and ponds.
Stoneflies
Stoneflies can be black, brown, orange or yellow or may be a combination of two of these colors. The stonefly is flat in shape and has two tails and the adult stonefly sports wings that fold flat across its back. This insect can be carnivorous or herbivorous and may eat mayfly or algae. Larvae are poor swimmers and are found under rocks or fallen trees.
