• 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.
