They live in warm regions, some growing to be as long as twelve inches or more. The "bite" or wound made by the poison claws is fatal to insects and other small animals, their prey, and painful or even dangerous to man. The popular notion that a centipede "stings" with all of its feet is falla- cious. It is recorded by Humboldt that centipedes are eaten by some of the South American Indians. The geophilids are very slender-bodied and usually rather long centipede-like forms with as many as 300 pairs of legs. They are usually yellowish and are common in damp places under stones or logs, or in the ground. Insects The great class Insecta, with its 350,000 known species, is a group of animals of special importance in the study of economic zoology. As we know but few more than 500,000 different kinds of animals altogether, it is apparent how dominant among animals, as regards numbers at least, the insects are. In fact we might well call this the Age of Man and FlG- 49-—A centipede , ... .,1 ..i i- Scolopendra sp. (Natural Insects, to contrast it with the earlier size S Age of Reptiles, Age of Fishes, Age of Invertebrates, etc. The insects include more kinds of animals directly injurious to the material welfare of man and to his health and duration of life than any other animal group. So it is that as students of economic zoology we must give insects, and their relations to man, a more detailed consideration than we shall give any other Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original Kellogg, Vernon L.
