The third instar of the immature male, called a "pro-pupa," is contained in a cocoon that begins forming toward the end of the second instar. It is 0.9 to 1.2 mm long and elongate-oval, with the head, thorax, and abdomen fused.
First and second instar larvae mine the leaves. The mines are widened gradually into one large blotch. Older larvae fold and web leaves to protect themselves and feed from inside these shelters.
A caterpillar goes through four instars, or developmental stages, before molting its skin one final time and becoming a chrysalis. Provide a stout branch on which the larva can attach itself when ready to pupate.
The first instar larvae have moved into cracks and crevices under bark where they will remain throughout the winter. The larvae hibernate until the following spring when they feed on new needles and developing buds.
The eggs will hatch in early spring and go through five Instars, or stages, before becoming adults. When the nymphs originally hatch in early spring, they will attach themselves to a plant and begin feeding.
