Cicadas True Bugs and Relatives: Hemiptera - Physical Characteristics, Habitat, Diet, Behavior And Reproduction, Hemipterans And People, Conservation Status - GEOGRAPHIC RANGE
species accounts found ocean
The hemiptera are found on all continents except Antarctica. They are even found on remote islands in the middle of the ocean. And they are the only insects that live on the surface of the ocean. There are about 82,000 species of hemiptera worldwide, with about 12,000 species in the United States and Canada.

The hemiptera are divided into four smaller groups based on their physical features. These groups include aphids, mealybugs, and scale insects; cicadas and hoppers; moss bugs; and true bugs. The relationships of whiteflies are uncertain, and they are sometimes included with aphids or hoppers. Hemipterans are extremely variable in form, ranging from long, slender, and sticklike, to short and round,…
Most hemipterans are active during the day. They spend most of their time feeding on plants, hunting for prey, and searching for mates and sites to lay their eggs. Some species, either as larvae or adults, gather in large, temporary feeding groups. Many species, especially true bugs, defend themselves with special glands that release bad-smelling and bad-tasting chemicals that repel their enemies.…
Hemipterans are used as food for both people and their pets. In parts of Mexico, humans eat egg masses of water boatmen that are fried or dried in the sun. Giant water bugs in India are cooked in syrup and are sold as an expensive treat. Female cicadas full of eggs are eaten in many countries throughout Asia. Stink bugs and their eggs are also dried and sprinkled on food like pepper. A reddish-pur…

Physical characteristics: The giant water bug is the largest true bug in the world, with adults reaching 4.5 inches (115 millimeters) in length. The body is uniformly pale to dark grayish brown. The forelegs are large, powerful, and adapted for grasping prey. The middle and hind legs are flattened for swimming. Males and females are similar in both size and appearance. The larvae resemble the adul…
Physical characteristics: A bed bug has a body that is rusty brown to dull red, flat, oval to round when not fed, and much fatter and longer after a meal. They measure 0.16 to 0.19 inches (4 to 5 millimeters) in length. The mouthparts are short and beaklike. The antennae have four segments. The front segment of the thorax or midsection is expanded so that it surrounds the back of the head. The leg…
Physical characteristics: The sea skater has a short, thick body, with a very short abdomen. They measure about 0.16 to 0.18 inches (4.0 to 4.6 millimeters) in length. The dull brown to black body is covered with a coat of small, silvery hairs. The head has a pair of yellow marks. Geographic range: They are found between the latitudes 40° north and 40° south, with most species living…
Physical characteristics: The backswimmer's body is widest at the middle. The head is rounded, while the abdomen narrows at the tip. They measure 0.31 to 0.35 inches (8 to 9 millimeters) in length.
