How Long Does It Take for a Bagworm to Turn into a Moth

When mature in mid-August, the larva wraps silk around a branch, hangs from it, and pupates head down. The silk is so strong that it can strangle and kill the branch it hangs from over the course of several years as the branch grows. Adult males transform into moths in four weeks to seek out females for mating.

What's the life cycle of a bagworm?

Life cycle of bagworms The adult female moth does not leave the bag the caterpillar created. She remains inside while the winged, male moth does emerge to fly about the infested tree to locate the waiting female. After mating the female produces 500 to 1000 eggs within her body and then she dies.

Are Bagworm moths harmful?

Bagworm larvae grow and feed on trees causing plant damage. These pests can be dangerous and costly to landscaping plants, but they pose no threat to human health. Large infestations of these pests may damage or cause trees and shrubs to die from defoliation.
