Odonata.—The dragonflies (fig. 9), "devil's darning needles," "snake doctors," etc., were familiar to every one of us when a child as objects of dread. However, they are perfectly harmless and may be handled without more than a slight pinch from a few of the larger sorts. They have long, slender bodies; long, many- veined wings; biting mouth-parts, and slender, bristly legs. The smaller kinds, called " damselflies," lay their wings together when at rest. They are predaceous, and catch many mosquitoes and other small Diptera. The larvre and nymphs are ferocious inhabitants of ponds and rivers, provided with extensile mouth-parts that can suddenly reach forward and catch an unsuspecting insect. The adult should be pinned and a slender hog- bristle pushed through the body from head to near the tail to prevent the loss of head, and keep the abdomen from bending downward. Some keep a few specimens of each kind in alcohol. The colors of some are apt to fade soon after death, so that color-notes should be made before killing the specimens. ORTHOPTERA. The members of this order have biting mouth-parts, and four stiff, many-veined wings. Those of the front pair, called tegmina, are long and thickened, and usually overlap at base when at rest. Those of the hind pan- are large and fold up like a fan, and are hidden by the tegmina. The head is large, and the legs rather stout; often the hind pair is en- larged and fitted for jump- ing. The younger stages, except for the absence of wings, resemble the adult, and a number of species never acquires wings, or at least only rudimentary ones. Their food habits vary greatly, according to the groups. There are five dis- tinct sections.
