DISTANCE FIRST-STAGE LARV^ CAN CRAWL, 29 seek places which are protected from the sun, and in such situations pupation takes place. The egg masses are deposited near the cases from which the females emerged. Hence it is seldom possible to find egg clusters on the upper sides of the branches or twigs of trees, because the lower sides furnish more protection and they are sought by the caterpillars before pupating. For this same reason it is usually possible to find many egg clusters on tree trunks just above the ground (PI. XL fig. 1), especially if there is grass or other mate- rial which would furnish protection. Many larva3, however, crawl from the trees and seek secluded places, sometimes at a considerable distance from their food plants, and rubbish piles, stone walls (PI. XL fig. 2), lumber piles (PI. Ill), outbuildings, or other protected places are often found badlv infested with egg The larva1 which hatch in such situa- tions must of necessity find suitable food if they are to survive, and the more traveling it is necessary for them to do to accomplish this purpose t h e greater chance there is that dispersion by the wind _ 0 _ . . . 1 J Pig. 2.—Female pupal case and egg clusters of jripsy Will take place.

After hatching takes place the larva? can commonly be found wandering about in search of food* They often crawl to the roofs of the buildings, and if they spin down from such a location, which often happens, there is ample opportunity for dispersion b}T the wind.
