• Dioryctria banksiella

  Dioryctria banksiella is a species of snout moth in the family Pyralidae, described in 1969 from Canadian specimens. The larvae develop within galls formed by the western gall rust fungus (Cronartium harknessii) on jack pine (Pinus banksiana) trunks. Early instars feed on gall tissue beneath the bark, while later instars mine deeper into the gall. The species is known only from western and central Canada.
