. Bulletin - Massachusetts Agricultural Experiment Station. Agriculture -- Massachusetts. CAPE COD CRANBERRY INSECTS 47 the very hind end. About thirty-two deep rusty-brown lines run along the body, some above, some below. There is a row of conspicuous white spots along each side, mostly above the .spiracles, most of them bordered with one black spot in front and another behind. The PujKi. The worms pupate in early and The jnipa is white, marked with black and yellow, and is about four-fifths of an inch long. It is formed in a slight but well-made net of yellowish threads among twigs or leaves or grass (fig. 33). This stage lasts about a month. The Moth. The moths fly in September and early October. They are so abundant some- tunes that the males come to street lights in clouds. The females fly little if not disturbed. Both sexes have snow-white wings marked with zigzag lines and dots of black (fig. 34). The face is deep yellow and there is a patch of yellow in front of the base of each fore wing. The antennae of the male are very bushy, those of the female threadlike. The male expands about an inch and a. half, the female an inch and Chain-spotted Geometer. Fig. 33. Pupae. Enlarged. Fig. 34. Male moth. The Eiiy. One female sometimes lays as many as 368 eggs. They are scattered in- discriminately on the ground, mainly in the latter half of September. They hatch the following spring. They are greenish yellow at first but become brownish lavender in a few days. They are about a thirty-third of an inch long and are broadly elliptical with one end flattened or somewhat cupped. Treatment. Spraying with 6 pounds of dry lead arsenate to 100 gallons of water is advocated. If this is done on the upland when the worms are small it will prevent trouble on the bog later. Keeping the marginal ditch cleaned out and partly full of water, as advocated for the gypsy moth, secures a bog from Please note that these images are extracted from s
