They are laid in the fine netting of the leaf, in which they are seen with great difficulty. The larvae hatch in from five to seven days. The young cater- pillar feeds on the upper surface of the leaf for a day or two, FIG. 332. The strawberry leaf-roller moth (Ancylis comptana Frohl. ) enlarged. (After J. B. Smith. ) eating into and along the midrib to weaken it. The young larva is at first a light green color with a large head and long hair, which becomes less noticeable as it grows. It soon ...commences to draw the edges of the leaf together, folding the upper surface on the midrib, holding it together by numerous strands of fine silk. The insect then spins a partial tube or lining inside, in which it remains until the moth develops. Unless disturbed the larva does not leave this folded leaf, and all the feeding is done out of the reach of sprays. The larva becomes full grown in about four weeks, when it is about half an inch long and of a dark-green color, until just before pupation, when it becomes more yellowish.
