The caterpillars of this moth sometimes do much harm in Raspberry plantations by destroying the buds and tunnelling up the shoots. The moth is 1/4 in. long, with wing expanse of 1/2 in.; front wings brown. The front wings have yellow spots, of which two on the inner border are the largest; on the outer border are three smaller spots and some still smaller ones at the base, and at the apical border a row of four small yellow specks; hind wings uniform brown; head yellow. The moth occurs from the end of May to June and lays her eggs in the blossoms, and in five to seven days the small larvae escape and tunnel into the cores of the berries. Here they remain a short time, and then leave the fruitlets and spin small flat cocoons of dull-grey silk, about 1/10 to 1/12 in. in diameter. These cocoons are found either under the soil, the rind of the canes, or in the stake crevices. Here the little larvae remain all the winter. In spring they crawl out and enter the buds and destroy them. Later, they tunnel up the shoots, which flag and die. The larvae in the buds and shoots are at first pink, then red, and, when mature, reach \ in. long. The larvae pupate where they have fed, the pupal stage lasting from nineteen to twenty-eight days.
Destruction in winter of all old canes and stakes and refuse on the soil. Smear the lower part of the canes in early March with soft soap to catch the ascending larvae, and repeat this again in two weeks' time.
