MOTHH AND BUTTERFLIES. 173 their habits, and can easily bo found at home, as they all go out to their meals regularly at nine , then return toward mid-day, and go out again at three o'clock , and return as soon as they have eaten. This destructive insect is found in all parts of the Union, and people having gardens or orchards should be careful to prevent its rav- iiges by destroying it in season. The Wood-tent Caterpillar {Clisiocampa sylvailca) is another not less noxious insect, gaining its own livelihood in the same destructive manner upon walnut and oak trees, although it is not unfrequently found also upon apple and cherry trees. When full grown, in June, it is about two inches long. Its head and body arc light blue, and its sides somewhat of a greenish color. It makes its cocoon and webs in the same manner as the- preceding ones, and some- times destroys whole orchards and large tracts of forests. The moths are of a dark-brown color, and its wings ex- pand about one and a half inches. The webs of these two species of caterpillars are made of the finest silk, and if properly collected and spun it could be manufactured intO" fine silk stockings or gloves—a profit- able amusement for the ladies spending the summer in the country. Span-ivormSi The Span-worms are little caterpillars, veiy injurious to vegetation, but quite harmless to man, although they are very annoying to all who walk through our orchards or parks during the month of June, by swinging against the face as they hang on the silken thread by which they let themselves down to the ground from the trees. The parks and promenades of our large cities—New York, Philadel- phia, Boston, etc.—abound with them, and they really af- loid a serious inconvenience to promenaders, and not un- frequently cause considerable fear to the timid upon whom ip w i m\V i.
