Hylobius congener
Seedling Debarking Weevil, Pine Weevil
Hylobius congener, the seedling debarking weevil, is a species of pine weevil in the beetle family Curculionidae. It is a documented pest of newly planted coniferous seedlings in clearcut forests, where adults feed on bark and frequently girdle and kill young trees. The species occurs in North America, with confirmed records in Canada including Alberta, British Columbia, Labrador, and Manitoba.
Longistigma caryae
Giant Bark Aphid
Longistigma caryae, commonly known as the giant bark aphid, is the largest aphid species native to the United States. First described in 1841 from pignut hickory in Massachusetts, this species was later placed in its own genus due to its distinctive extremely long, slender stigma that extends around the end of the wing. It feeds on the bark of hickory trees and has been documented across eastern and central North America.
