Food
Jack, red, shortleaf, loblolly, slash, longleaf, pitch, and Swiss Mountain pines are preferred. They may defoliate white pine, larch, deodar cedar, and Norway spruce if they are growing near their preferred species(1)
It prefers young trees; ones that are 1-15' tall.(1)
In the South, it prefers trees growing in shaded areas.(1)
Life Cycle
Overwinter in the prepupal stage.(1)
Eggs are deposited in the tissues of current or previous year's needles. A single female can lay up to 100 eggs. The larvae feed gregariously on new and old needles completely defoliating a branch before moving to another. Defoliation progresses from the top downward before the larvae reach maturity. Full-grown larvae drop to the ground, enter the soil, and spin tough, reddish-brown cocoons where they spend the winter.(1)
In the south there can be 5 generation per year, in the north only one.(1)
Remarks
