PSYCHIDAE

(Bagworm or Bagmoths)

The Psychidae (bagworm moths, also simply bagworms or bagmoths) are a family of moths the males of which have thinly scaled or nearly transparent wings while the females are wingless and wormlike. A bagworm begins to build its case as soon as it hatches. Once the case is built, only adult males ever leave the case, never to return, when they take flight to find a mate. Bagworms add material to the front of the case as they grow, excreting waste materials through the opening in the back of the case. When satiated with leaves, a bagworm caterpillar secures its case and pupates. The adult female either emerges from the case long enough for breeding or remains in the case while the male extends his abdomen into the female's case to breed. Females lay their eggs in their case and die.
