38 INSECTS OF ECONOMIC IMPORTANCE 



flat, and close to the head, hence the name ; the larva 

 attacks many kinds of fruit-trees, forest and shade- 

 trees, infesting by preference those diseased or dy- 

 ing; it inhabits all parts of the trunk from ground 

 to branches; eggs are laid in cracks of bark; the 

 larva lives just beneath the bark and burrows out 

 broad, flat, irregular channels in the wood; as it 

 grows it may go deeper into the wood ; it matures in 

 one year and the beetles emerge in May and June; 

 the adult beetle has short antennae, is of a dark 

 metallic brown color, and about one-half inch long. 

 Control — Same as for the round-headed borer. 



The bud-moth^ (Tmefoccra ocellana) 

 Order — Lepidoptera. Manual, p. 241 



A most important pest on the apple in New York. 

 The tiny dark brown caterpillars appear early in 

 the spring and begin to attack the bursting buds; 

 they bore into the buds and when the leaves begin 

 to unfold attack those also ; they continue to eat the 

 leaves and tie them together, finally pupating with- 

 in the tangled mass ; the moths appear in June and 

 lay their small inconspicuous eggs on the leaves; 

 these hatch in about 10 days and the tiny caterpil- 

 lars feed on the surfaces of the leaves eating the 

 epidermis and tissues away, leaving a network of 

 veins; the caterpillar lives mostly in a tiny silken 

 tube built along the midrib of the leaf; in Septem- 

 ber the caterpillars migrate from the leaves to the 

 small branches where they build snug silken cases, 

 called hibcrnaciila, in which to pass the winter; 

 these hibernacula are built very often near the buds 

 where the larvae will find food close at hand in the 

 spring. There is only one brood a year. 



Control — Add arsenate of lead, 2^2 pounds to 

 50 gallons, to the delayed dormant spray just as the
