The Cranberry Spanworm (Cleora pampinaria Guen.) The leaves of cranberry, asparagus, cotton, strawberry, apple, pear, clover, and others are sometimes eaten by a brownish or olive span- worm, Ij inches long when mature. Its body is streaked and mottled with Ughter and darker shades. On the back, about one tliird of the way to the rear of the head, are two low black tubercles, and near the hind end are two more. There are two pairs of fleshy false legs near the hind end, and three pairs of true legs close to the front end. The worms have a habit of resting motionless, hold- ing fast to a stem by the hind legs, the body projecting at an angle. The adult is a gray moth marked with many spots and zigzag lines of black and brown. There are two generations annually, larva; appearing in late June and again in August. Dusting or spraying with arsenate of lead or Paris green will poison the worms. The Elm Spanworm (Ennomos subsignanus Hbn.) In June the larvae of this moth may be found on the foliage of a great variety of trees, including apple, pear, or other fruits as well as forest trees. Usually they are brown, but sometimes green, look much like a twig, and have three low tubercles on the back, one near the hind.
