Bagworms overwinter in which form?

Bagworms overwinter in which form?

• A. Eggs within the female's bag
• B. Larvae in cocoons
• C. Pupae in soil
• D. Adults in tree crevices

Answer: (A)

Bagworms overwinter as eggs inside the protective bag made by the female. The female stays in her bag and lays eggs there, and those eggs endure the winter until spring when they hatch into young larvae that begin feeding on host plants. This is why removing and destroying bag-containing bags in late fall or before they hatch is an effective control. They do not overwinter as larvae in cocoons, pupae in soil, or adults in tree crevices—the wintering stage is the egg in the bag.
