Larvæ are now feeding freely, and a few hours spent in beating, sweeping, and searching will enable you to stock your cages liberally.
Sugaring may be continued throughout the month, and the sallow blossom may be searched as long as it proves attractive. Moths may also be attracted by light at night.

MAY
Little or nothing will be obtained by digging during May, yet a number of pupæ may be found among grass and leaves under trees, and also attached to the leaves and stems of low plants. These pupæ include those of several of the butterflies, among which may be mentioned Machaon, Selene, Euphrosyne, Aurinia, Megæra, Ianira, Rubi, Astrarche, Icarus, Bellargus, Corydon, Lucina, and Sylvanus.
