bug (bŭg) Pronunciation Key
Our Living Language : The word bug is often used to refer to tiny creatures that crawl along, such as insects and even small animals that are not insects, such as spiders and millipedes. But for scientists the word has a much narrower meaning. In the strictest terms bugs are those insects that have mouthparts adapted for piercing and sucking. The mouthparts of these bugs are contained in a beak-shaped structure. Thus scientists would classify a louse but not a beetle or a cockroach as a bug. In fact, scientists often call lice and their relatives true bugs to distinguish them better from what everyone else calls "bugs." |
true bug (tr ) Pronunciation Key
Any of various insects of the group Heteroptera. True bugs usually have soft flat bodies, well-developed antennae, and stink glands. They include the water bugs, water striders, bedbugs, cinch bugs, lace bugs, and assassin bugs. Some scientists classify the true bugs as a suborder of the order Hemiptera rather than as a separate insect order. See Note at bug. |
true bug
any member of the insect order Heteroptera, which comprises the so-called true bugs. (Some authorities use the name Hemiptera; others consider both the heteropterans and the homopterans to be suborders of the Hemiptera.) This large group of insects, consisting of more than 40,000 species, can be recognized by an X-shaped design on the back, which is formed by the wings at rest. A combination of features-sucking mouthparts adapted to pierce plant or animal tissues and a hardened gula (underside of the head)-separate the heteropterans from all other insect orders. Although most species of Heteroptera are terrestrial, a few are aquatic. Some species, which feed on plant juices, are serious pests of cultivated crops; other species are predacious and benefit man by destroying various pests. There also are heteropterans that act as carriers of disease.
