The key to insect success is their ability to survive on land and take to the air. In North Carolina, soil samples to a depth of 5 inches yielded a calculation that there were approximately 124 million animals per acre, of which 90 million were mites, 28 million were springtails, and 4.5 million were other insects.

It also contains detailed information on all the 558 families of British insects. Certain social insects have large numbers in their nests. Insects are distinguished from other arthropods by their body, which is divided into three major regions: (1) the head, which bears the mouthparts, eyes, and a pair of antennae, (2) the three-segmented thorax, which usually has three pairs of legs in adults and usually one or two pairs of wings, and (3) the many-segmented abdomen, which contains the digestive, excretory, and reproductive organs. Mouth Parts: They have piercing and sucking mouthparts. Many form colonies with different and distinct roles. Wings: As adults they have two pairs of large wings covered with protective scales. They split and spread when the insect needs to fly so the soft wings underneath (hind wings) can be used. 10 extinct), depending on authority, up to 1000 families, and well over a million species.

We are sometimes asked about what worms are. They hatch from underwater larva and fly above the water, mate, lay eggs and die. All rights reserved. Dragonflies hold their wings flat and out from their bodies, while damselflies hold their wings together and pulled into the body. The largest numbers of described species in the U.S. fall into four insect Orders: Coleoptera (beetles) at 23,700, Diptera (flies) at 19,600, Hymenoptera (ants, bees, wasps) at 17,500, and Lepidoptera (moths and butterflies) at 11,500.

What are the differences between butterflies and moths? Moths, butterflies and skippers: Order Lepidoptera. Insects, like allanimals, are classified using ahierarchical system of classification. From studies conducted by Terry Erwin of the Smithsonian Institution's Department of Entomology in Latin American forest canopies, the number of living species of insects has been estimated to be 30 million. Metamorphosis: They undergo incomplete (simple) metamorphosis with the nymphs looking like small versions of the adults (with underdeveloped wings).

Together these features can help us distinguish insects from other arthropods. Both have larvae that can be destructive to trees and food crops. Mouth Parts: Adults have sucking mouthparts. To appreciate the population potentials of insects the example of the housefly is sometimes used, stating that the descendants of one pair of this insect, provided that they all survived during a five month season, would total 190 quintillion individuals. 2) Mantid & Cockroach Order Dictyoptera Examples of Families: They have long, thin antennae with many segments. 1) Beetle Order Coleoptera Examples of Families: The order Coleoptera includes the beetles. Observations on the Microfauna of the Duke Forest. The first insects probably appeared before the Devonian period (400 - 360 million years ago) and by the Carboniferous period (360 - 285 million years ago) had taken to the air. These are appendages that serve the purpose of legs. In the world, some 900 thousand different kinds of living insects are known. Moths have more feathered antennae and hairier bodies than butterflies. The straight-winged insects, Order Orthoptera, and the skin-winged insects, Order Dermaptera. These great numbers of insect species and individuals were created by a number of factors including their long geological history, the capability of flight, their small size that allows survival in many various habitats, their ability to store sperm for delayed fertilization, and their general adaptive abilities to the environment. Wings: They usually have two pairs of wings.

These amazingly diverse animals have conquered all the environments on earth except for the frozen polar environments at the highest altitudes and in the immediate vicinity of active volcanoes. inInsects: The Yearbook of Agriculture. Insects are the only invertebrates (animals without backbones) with wings. They are so well camouflaged that they move slowly on their food plants and are rarely seen by predators. The more recently evolved Hymenoptera (ants, bees, wasps and sawflies) and Lepidoptera (butterflies and moths) appear as fossils in the Jurassic period (210 - 145 million years ago). A recent article inThe New York Timesclaimed that the world holds 300 pounds of insects for every pound of humans. Insects play a very important role in the web of life, in every environment.
