Explanation of Names
Pini is Latin for "pine." (1)
Size
Wingspan: ♂ 28-32 mm, ♀ 32-34 mm. (2)
Larva to about 25-27 mm (Kellicott, 1881).
Pupa about 18 mm (Kellicott, 1881).
Identification
Larva - body white with a light brown head. (Kellicott, 1881).
Range
Midwestern states east to southeastern Canada, New England south through the Appalachians. (2)
Season
The males are strongly attracted to ZZOH/EZOH 50:50 pheromone lures and are on the wing starting in late June in Michigan.
Food
Larvae bore under the bark of pine and spruce, principally eastern white pine (Pinus strobus, Pinaceae) (2), sometimes Norway spruce (Picea abies, Pinaceae). Larvae typically bore in large trees below a broken branch or scar as high as 40' up the trunk (Kellicott, 1881). (2)
Life Cycle
Eggs are laid in June and July near a wound, old scars, or just below a branch. The larvae bore into the inner bark and sapwood, excavating transverse tunnels and cause copious flows of pitch. This pitch accumulates in masses 3-4" in diameter at the entrance hole. Pupation occurs in the pitch mass and when the moth emerges the empty pupal case is left sticking out of the mass.(3)
Life cycle requires 2-3 years.(3)
Remarks
It is found rarely in insect collections and museums. Trees with active larvae have pitch mass swellings on the tree trunk with a white, powdery appearance. (4), (2)
