Inchworms turn into moths during their life cycle so when you see an inchworm the inchworm will eventually turn into a moth and be able to fly around.
Inchworms use silk threads to lower themselves to the ground from trees and then they use that silk thread to also create a cocoon.
The inchworms larvae burrows into the dirt or leaf litter and then spins protective cocoons to become pupae and then in the spring the inchworm then leaves it's cocoon and becomes a moth.
If the inchworm larvae emerged in summertime, it will live as a pupae in the ground during winter and then emerge as an adult moth in spring.
Pretty amazing how they can do that.
