ट्रिगर

The damage is caused by the larvae of Kophene cuprea. The adult moth is brownish in color. Bag worms pass the winter as eggs (300 or more) inside bags that served as cocoons for the females in the previous year. When the eggs hatch, the larvae crawl out to feed. Each larvae uses silk and bits of plant material to make a small bag which serves as a camouflage during it's feeding and growth. The caterpillar of Bag worms feed for about six weeks, enlarging the bags as they grown and withdrawing into it when disturbed. Older larvae strip evergreens of their needles and devour whole leaves leaving only the larger veins. The brown larvae are covered in conical bags. In early fall, mature larvae attach their bag to twigs and transform into the pupa or resting stage before becoming an adult.
