Evergreen bagworm in forested areas are rare. With scarce predators in urban areas, evergreen bagworms often thrive in urban habitats. When disturbed, the larva will retract its head into its case and hold the front opening closed. Mature larva may remain in the host tree or drag its case nearby before attaching itself for the pupa stage. Arborvitae and red cedar are the favored host trees of the evergreen bagworm, but cypress, juniper, pine, spruce, apple, birch, black locust, elm, maple, poplar, oak, sycamore, willow, and over 100 other species are also attacked. Leaves and buds are both fair game for food.
Juniper berry 8–10 months in a few species, and about 24 months in "J. drupacea"). The mature, dark berries are usually but not exclusively used in cuisine, while gin is flavoured with fully grown but immature green berries. The flavor profile of young, green berries is dominated by pinene; as they mature this piney, resinous backdrop is joined by what Harold McGee describes as "green-fresh" and citrus notes.
