A small greenish or brownish caterpillar folds the leaflets of the strawberry by bringing the upper surfaces to- gether and fastening them by silken cords (Fig. 276"). In this retreat the insect spends its whole larval life, feeding upon the leaf, and ultimately causing it to turn brown and shrivel up. The transformation through the brown pupa to the adult insect—a pretty little brown moth—takes place within the folded leaf. There are two annual broods of the pest in the.

Spraying with poisonous mixtures is impracticable -while there is fruit on the plants, and experiments indicate that such applications are not very effectual at any time, so se- curely protected are the feeding-grounds of the caterpillars. However, it is claimed that the pest can be almost exter- minated in a field by mowing it after the crop is gathered, and after leaving it a day or two to become dry, burn it over, per- haps with the aid of a little straw or rubbish. This can usually be done without the slightest injury to the plants. This will destroy the leaf-roller as well as several other kinds of insects,.
