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 wingspan is 22–25 mm. Adults are grey to brownish. The basal third of the forewing is dark grey to black, while the rest of the forewing pale grey, becoming darker grey toward the outer half. The hindwings are brown with darker shading toward the outer margin. The number of generations per year varies from three in north-eastern Florida to one in the northern part of the range. In Florida, adults are on wing from April to October. 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. ==Gallery== Image:Pococera robustella larvae.jpg|Larvae Image:Pococera robustella damage.jpg|Damage Image:Pococera robustella damage1.jpg|Damage 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Pococera robustella」の詳細全文を読む スポンサード リンク
