1-d Paper wasp's slender, elongated bodies are black, brown or red with yellow markings. Their nests are made of a paper-like material that forms a circular comb of cells which opens downward. The nests are often located under eaves, behind shutters, or in shrubs or woodpiles.
2-g Yellow jackets are black with yellow markings and are found in various climates. Their nests, which are made of a papier-mâché material, are usually located underground, but can sometimes be found in the walls of frame buildings, cracks in masonry or woodpiles.
3-a Hornets are black or brown with white, orange or yellow markings and are usually larger than yellow jackets. Their nests are gray or brown, football-shaped and made of a paper-like material similar to that of yellow jackets' nests. Hornets' nests are usually found high above ground on branches of trees, in shrubbery, on gables or in tree hollows.
4-f Honeybees have a rounded, "fuzzy" body with dark brown coloring and yellow markings. Upon stinging, the honeybee usually leaves its barbed stinger in its victim; the bee dies as a result. Honeybees are not aggressive and will only sting when provoked. However, Africanized honeybees found in the southwestern United Stated and South and Central America, are more aggressive and may sting in swarms. Domesticated honeybees live in man-made hives, while wild honeybees live in colonies or "honeycombs" in hollow trees or cavities of buildings. Africanized honeybees may nest in holes in house frames, between fence posts, in old tires or holes in the ground or other partially protected sites.
5-b Fire ants are reddish brown to black stinging insects related to bees and wasps. They build nests of dirt in the ground that may be quite tall, up to 18 inches, in the right kinds of soil. Fire ants may attack with little warning: after firmly grasping the victim's skin with its jaws, the fire ant arches its back as it inserts its rear stinger into the skin. It then pivots at the head and may inflict multiple stings in a circular pattern. Fire ant venom often causes an immediate burning sensation.
6-c Bumblebees are black and yellow and both the thorax and abdomen are hairy. Bumblebees rarely cause sting reactions because it is easy to avoid these slow, noisy insects.
7-e Female mosquitoes are the ones that feed on humans. In order for a bite to cause swelling, the mosquito's contact after puncture must last approximately 6 seconds. It is thought that the chemicals in the saliva of the mosquito are responsible for the swelling and itching that follows the bite.
