The Pine Webworm Moth (Pococera robustella) is a species of moth of the Pyralidae family. It is found in southern Canada and the eastern United States from Minnesota to New England and south to Florida. The larvae feed on the needles of various Pinus species. Young larvae mine the needles of their host plant. Later, they spin a nest of silk webbing and frass. They gather needles from around their nest and bring them back to the nest to eat. The web is occupied by several larvae. The larvae are light brown with darker longitudinal stripes and a light brown head with black pigmented markings.
