11.Each instar of larvae stage is green.
Caterpillars stay at the same tree they hatched. Trees are not harmed in any significant way as the moth population is not large enough.
12.Luna moth cocoon is single-layered and wrapped in leaves.
Pupa is attached to a silk pad at the rear of a cocoon with a hook-shaped protuberance called cremaster.

15.Favorite host plants for luna moths are broadleaf plants.
Northern populations often utilize white birch while southern pick walnuts, hickories, sumacs, sweetgum and persimmon.
