The wings of butterflies are alwaj's clothed with scales that overlap like shingles on a roof (Fig. 104). They undoubtedly aid in strengthening the fling. When the scales are all removed from the fling, it appears as a thin trans- ])arent memljrane flith vems running lengthflise and flith fefl^ cross veins (Fig. 105). The fl'uigs of the butterfly are never folded like those of the locust, but are held vertically fliien the insect is at rest. The legs of the butterfly. âAlthough this insect has six legs they are fl'eak and are little used for locomotion but rather for the pm-pose of clinging to objects upon which the insect may alight. Again, although the hind legs are larger than those of the other pairs they are not large and muscular like the hind legs of a locust and are not used for Fig. 103.âfl'liite cabbage butterfly, lar^â¢a, and 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 Herrick, Glenn W.
