If the trees are already attacked,jarring the limbs will cause many of the worms to spin a threadand drop to the ground. If the band of tanglefoot is in placethey will be unable to return to the attack and may be destroyed. Perhaps the best way of fighting this pest, however, is byspraying with arsenate of lead, giving one application justbefore the blossoms open and a second after the petals fall. MAINE AGRICULTURAL EXPERIMENT STATION. 25 Cecropia Moth.(Samia cecropia.) The large gray or brown cocoon of the Cecropia moth is fre-quently found attached to the twigs of trees (fig. 37).. Fig. 7. (From Me. Agr. Exp. Sta. Circular). These are spun late in August or September by a green cater-pillar about four inches long. The body of the caterpillar isornate with colored bead-like tubercles, the two pairs nearestthe head being red with black spines, and the other dorsal tuber-cles smaller and yellow. Along the sides of the body the tuber-cles are bluish, (fig. 7), After the cocoon is spun the caterpillar changes to the pupa,a dark brown object which may be found by opening one ofthe cocoons during the winter. In the spring the insect breaks open the brown pupal skinand emerges from the cocoon as the adult insect, the largestmoth in the state and one of the most beautiful. Its expandedwings measure about five and one half inches. In color thewings are brownish with a border of gray and submarginallines of white and red. The form of the markings is betterrepresented by the accompanying illustration than by a des
