Weymouth-Kiefer
There is one flight from March to April in the south, while it occurs between mid-May and early June in the north. Females will lay eggs singly on flower buds. The caterpillars eat both the flower and the developing seedpods. Chrysalids hibernate in loosely formed cocoons beneath litter below the plant. Larval foods include jack pine ("Pinus banksiana") and white pine ("Pinus strobus").
