. Text-book of zoology for junior students. Zoology. nnUEllS OF IXSECTS. I', thing on theii- line of march is destroyed, every leaf is stripped from every tree, every blade of grass and coin is eaten down, and it is not until the ground is utterly bare and brown that the Locusts take wing and seek out some fresh region to devastate. Neai-ly or quite as destructive as the Eastern Locust are various species which inhabit North America, and are particularly abundant in the far West. Order VII. The mouth in this order is fitted for mastication ; the wings are four in number, generally nearly equal in size, all membranous, and traversed by numerous delicate neivures, which interlace so as to form a delicate network (tig. 119). The metamorphosis is generally incomplete, but is sometimes complete. This order includes the well-known and rapacious Dragon-Hies (LibelluUdce), the Caddis-flies {Phryganeidie), the May-flies (Eplumti'- ridie), the Ant-lion [Myrmdco), the Aphis-lion (fig. 119), Termites, &c. The last of these—namely, the Termites or White Ants ( Fig. 119.—Neuroptera. K\Ai\s-\iu\\{ChnjiOpa i^cd"), iinngo, larva, and eggs. 120)—are social insects, living in organised communities, and ex- hibiting many remarkable phenomena. They are mostly inhabi- tants of hot countries, and cause immense mischief b_y destroying wood-work of all descriptions. Though called " White Ants," it is to be remembered that they are not related in any way to the true Ants. They build mounds of different shapes and sizes, sometimes several feet in height, formed of " particles of earth worked into a material as hard as ; Each family of Termites possesses a king and queen, which are always kejit together closely guarded in.
