12, 13).
For Maine the saddled prominent has but one brood. The moths emerge in greatest numbers late in May and early in June. Oviposition begins soon after mating which occurs the first night after emergence. The eggs hatch in about 9 days and the larvae become full grown in 5 weeks (or more accord- ing to weather conditions and food supply). During this time they molt four times. The full grown larvae enter the ground for pupation. In Maine pupation takes place from mid July to late August, ...the majority of larvae burying late in July. They pass the winter in the pupal stage, under the leaf mold, and the moths emerge in the spring.
The eggs are deposited singly by the female which in cap- tivity applies the eggs to both sides of the leaf. From the rea- son that the tops of the trees are stripped first and then the lower branches it is to be concluded that the moths by prefer- ence deposit the eggs upon the upper leaves. Perhaps the same tendency to fly high may account in part for the fact that the 26 hillside forests are in general more largely attacked than the lowlands.
