Psychidae, commonly known as bagworms, are a family of moths characterized by their unique larval stage. The larvae create protective cases or bags from materials like leaves, twigs, and silk, which they carry as they move. These bags serve as camouflage and protection from predators. Adult bagworms are typically wingless and emerge from their cases to mate. They are found in various habitats, often in forests and gardens, where they can be pests to certain plants. The life cycle of Psychidae includes distinct stages: egg, larva, pupa, and adult, with the larval stage being the most recognizable.
