. Birds of other lands, reptiles, fishes, jointed animals and lower forms;. Zoology; Birds; Reptiles; Fishes. SCALE-WINGED INSECTS Si 3 The expansion and contraction of the muscles pump air into the hollow tubes which form the framework of the wings; these rapidly expand to their full size, and become dry and firm at the same time. After this, the insect flies about with its companions, pairs, lays its eggs, and then dies, after enjoying its life for a period, varying according to the species and the season, from a few hours to several months. We have not yet spoken of the feelers, or antennae, of butterflies and moths. They are two long, jointed organs, nearly always knobbed at the end in butterflies, or at least the terminal joints are thicker than the rest. But in moths the antennae are of ditterent shapes, and generally end in a point. Sometimes they are simple and thread- like ; sometimes they are thickest in the middle, and thinner at both ends, as in the Hawk-moths; and they are often comb-like, especially in the males, as in the Silk-moths. Butterflies As already mentioned, butterflies may be distinguished from moths by. rholo by Hi^hlt.
