bagworms
Silk-wrapped tree pests
Bagworms are moth larvae that construct protective cases from silk and plant debris, carrying these bag-like shelters as they feed.
The caterpillars are garden pests, often damaging evergreens and ornamental trees: The junipers were infested with bagworms.
The adult females remain wingless and never leave their bags.
