Thecaterpillars get theirgrowth in 2 or 3weeks, and are thenabout f of an inchlong, light green incolor with the head,legs and thoracic shield varying from brown to black. About tendays are spent as a brown pupa (Fig. 68) in a delicate silken webor cocoon in the nest early in June. The moths emerge, and soon lay the peculiarpatches of eggs onthe bark, thus com-pleting the life-cycleof the single annualgeneration of thisleaf-roller. Thepretty little moths,measuring about f ofan inch across theexpanded wings, varyconsiderably in coloring and markings (Fig. 69).
