Bagworms - Cocoon(s)
(Lepidoptera: Psychidae)Bagworms are caterpillars that prefer to feed on juniper, arborvitae, and Leyland cypress, but will eat a variety of other deciduous and coniferous plants.Early in the season, look for the 'dunce-cap' stage of feeding-•small larvae that carry their bags in an upright position. As they continue to grow, the bag hangs down in the commonly seen fashion. Egg hatch may continue until about mid-June for some isolated groupings of bagworm eggs.
