The females lack wings and are so heavy with eggs that they just crawl up the tree trunk until males find them and mate with them. The females lay their eggs on twigs, and sometimes on nearby wooden fences. The eggs will hatch into the small green "inch worms" as leaves break next spring. Photo: Linda Hawkins, Four Seasons Tree Care. Adult fall cankerworms will mate and lay eggs as late as November.
