Winter Burrow Cut Open THE BUTTERFLIES AND MOTHS ~ ±17 ' The life history of this pest" in California has been very carefiilly worked out by the investigators of the State Ex- periment Statio"!!. In brief it is as fbllows: Throughout thefall and winter the ^mall caterpillars are hidden within curious cells that they make in the bark of the trees,' es- pecially in the forks of â ⢠the ^ These lit; tie burrows are furnished with a silken lining, and are covered with a sort of thatch made by fasten- ing tiny bits of bark to- gether with silk. With in these hibernating' cellsj the insects are protected from most dangers. Early in spring, the^larvae become active and get ready to emerge from their winter quarters by tearing away a part of the protective covering. Finally they emerge and attack the young buds, burrowing their way into the pith of the short branches. They thus become twig borers, and often do grfeat damage. , â ; After a fe^ weeks of this ejJistence, they hide;within the bits of-ctirlfed--bark upoii the trunk- and larger brainches^ where they change to pupae, generally very sligi^itlysheU tered by a few silken hairs. These pupae shortly change again into adult nioths, that lay their eggs on the bark of the young twigs. ; These eggs soon hatch into tiny larvae, which also becom'e twig borers during the first weeks of their life, usually upon a tree loaded with'iruit. This brood of worms lives as'twig borers for three weeks. They then leave and burrow into the green peaches, entering at the stem end and feeding freely upon.
