Neodiprion swainei, the Swaine jack pine sawfly, is a species of sawfly in the family Diprionidae.[1] It is found east of the Rocky Mountains in Canada from Alberta to Nova Scotia and in the Great Lake states of the United States.[2][3]

Its primary host is the jack pine. Larvae feed more readily on older growth because current-year foliage contains a chemical deterrent.[2] Other pines that may be defoliated if near an outbreak of this sawfly include red (Pinus resinosa), eastern white (Pinus strobus), and scotch (Pinus sylvestris) pines.[4] Only minor infestations have occurred north of 49° N due to the low survival rate of larvae in the cold fall weather.[2]
