Older larvae consume the entire leaf, except the midribs and major veins.
Eggs hatch at about the time of bud break, and the young larvae begin feeding on the expanding foliage. Feeding continues for approximately 6 weeks, then the mature larvae enter the soil and pupate. Other natural enemies also help in control. Sticky bands placed around the trunks of high value trees can trap the females as they climb the tree to lay eggs. In high use or high value areas, chemical control may be needed.
