Brown Marmorated Stink Bug
Brown marmorated stink bugs grow to be less than an inch long, and they are brown both on their backs and on the lower side of their abdomens. They are as wide as they are long, and they can be distinguished from similar insects by patches of coppery or bluish depressions in on their heads and light bands on their antennae. They feed on plants and when found inside the home, they eat food left out. They have well developed scent glands that allows them to produce a strong smell when they are startled.
Green Stink Bug
The green stink bug is found throughout the eastern and western United States, along both costs. It is the most common stink bug in North America, according to the University of Florida. It has fully developed wings underneath solid light green wings, and their heads tend to be lined with a yellow-orange stripe. They are less than an inch long. They attack developing fruit trees by eating the leaves and the fruit, and their punctures allow bacteria to enter the fruit. They also lay their eggs in fruit trees.
Southern Stink Bug
The Southern green stink bug ranges between ½ to ¾ inch in length, and it is a solid green. They eat both fruit and ornamental trees and they can also severely hurt soybean and cotton crops. They leave behind deformed fruit that has sunken, drawn dimples on them, and in cases where they injure ripened fruit, they leave behind a hard, off-color mass in the middle of the fruit.
Spined Soldier Bug
Spined soldier bugs are about 1 inch long, and they have a hard, sharp spine protruding from their heads. They range in color from yellow to light brown and they are lightly covered with black specks. Unlike other common stink bugs, they are predatory, feeding on grubs and caterpillars. This makes them a welcome addition in the garden, where they eat many harmful pests.
