The fall canker-worms {Anisopteryx pometaria, Harr.) emerge fromthe ground late in the fall, after the leaves have fallen from the treesand frosts have appeared. The females climb the trees attended bythe males which hover around on the wing. After the mating of themoths, the females lay their eggs side by side in regular masses,Fig. 3, e, often as many as a hundred together, in an exposed situa-tion on the twigs or branches of the trees. Sometimes the females,by mistake, crawl up on the side of a building and deposit theirclusters of eggs on the exposed Fig. 3. Fall Canker-Worm. a, b, Egg, side and top views; c, d, joints of larvae, side and top views, showing mark-ings, enlarged; e, cluster of eggs; /, full grown larva; g, female pupa, natural size;h, cremaster enlarged.—After Riley. The eggs are in the form of a truncated cone, and attached by thesmaller end, while the other end has a dark rim with a depressedcenter, Fig. 3, a and b. These hatch in the spring at about the sametime as the other species, and the larvae have similar habits to thoseof the spring species. The mature lai-vae are nearly an inch long, varying in color froma greenish yellow to dark brown, with pale stripes running length-wise ; and they differ from the other species still further in havingthree pairs of abdominal legs, Fig. 3, /. After they are donefeeding, they descend from the trees and burrow into the groundwhere they pass their transformations, and the moths emerge late inth« fall.
