CHAPTER VIII INSECTS THE GRASSHOPPER SUGGESTIONS. - - Collect grasshoppers, both young and full- grown, and keep alive in broad bottles or tumblers and feed on fresh grass or lettuce. When handling a live grasshopper, never hold it by its legs, as the joints are weak. To keep them for some time and observe their molts, place sod in the bottom of a box and cover the box with mosquito netting or wire gauze. What is the general shape of its body? (Fig. 106.)

CHAPTER VIII INSECTS THE GRASSHOPPER SUGGESTIONS. - - Collect grasshoppers, both young and full- grown, and keep alive in broad bottles or tumblers and feed on fresh grass or lettuce. When handling a live grasshopper, never hold it by its legs, as the joints are weak. To keep them for some time and observe their molts, place sod in the bottom of a box and cover the box with mosquito netting or wire gauze. What is the general shape of its body? (Fig. 106.) Where is the body thickest ? Is it bilaterally symmetri- cal, that is, are the two sides of the body alike ? Is the skeleton, or hard part of the body, internal or external ? Is the skeleton as stiff and thick as that of a crawfish ? What is the FIG. 106.—A GRASS- length of your specimen ? Its. color ? Why does it have this coloration ? In what ways does the grasshopper resemble the crawfish ? Differ from it ? The Three Regions of the Body. - The body of the grass- hopper is divided into three regions, — the head, thorax, and abdomen. Which of these three divisions has no distinct subdivisions ? The body of the grasshopper, like that of the earthworm, is made of ringlike segments. Are the segments most distinct in the head, thorax, or abdomen ? Which region is longest ? Shortest ? Strongest ? Why ? Which region bears the chief sense organs ? The ap- pendages for taking food ? The locomotory appendages ? Which division of the body is most active in breathing ? 63.
