The true bugs are a large and diverse group of about 35,000 species of insects in the order Hemiptera. About 44 families of bugs occur in North America. Bugs typically have a flattened body, and their folded wings cross over their thorax and abdomen, giving a distinctive, cross-like pattern.
Some species of true bugs are of great economic importance as pests of agricultural plants. A few species of bugs are vectors of important diseases of humans.
In popular usage, the word "bug" is often used to refer to non-hemipteran insects, and not only to "true bugs." When used to refer to a species in the Hemiptera, the "bug" part of the name should be written separately, as in: stink bug, or milkweed bug. When used to refer to non-hemipteran insects, the "bug" part of the name should be used to form a single word, as in: ladybug (a family of beetles, order Coleoptera), or mealybug (scale insects, order Homoptera), or sowbug (Crustaceans in the order Isopoda, which are not even insects).

The true bugs have an incomplete metamorphosis, characterized by three life-history stages: egg, nymph, and adult. The nymphs resemble the adults somewhat in form, but they are not capable of reproduction. Most North American bugs overwinter at the adult stage. Bugs have two sets of wings. The forewings of most species of true bugs are rather tough and leathery towards their base, and membranous f…
The most diverse family of bugs is the plant or leaf bugs (family Miridae), species of which can be found in terrestrial habitats world-wide. Almost all plant bugs feed on the juices of plants, some species causing important damages to agricultural crops. Important agricultural pests include the tarnished plant bug (Lygus lineolaris), which feeds on a wide range of crop plants, the apple red bug (…
The water boatmen (family Corixidae) are common aquatic bugs that swim in the water column of lakes and ponds. The hind legs of water boatmen are oar-like in appearance, being long and flattened, and are used for underwater locomotion. Water boatmen do not have gills for the exchange of respiratory gases—they must breath head-first at the surface, although most species can carry a small bub…
Bed bugs (family Cimicidae) are wingless bugs with a body length of about 0.2 in (6 mm). Bed bugs feed by sucking the blood of birds or mammals. Various species will bite humans, and they can be serious pests in homes, hotels, and other places, especially the common bed bug (Cimex lectularius). Bed bugs come out at night, hiding during the day in cracks and crevices in walls and furniture. The bit…
