Background Information

The gypsy moth, Lymantria dispar, is in the same category of insects as moths and butterflies. This group of insects, called Lepidoptera, is known for both their beauty and their destructive nature. The gypsy moth belongs to the family Lamantriidae, which is characterized by feeding on tree foliage. Lamantriid larvae are also known as tussock moths because of the prominent tufts of hairs along their body.

The gypsy moth goes through complete metamorphosis. The egg hatches larvae that grow and complete several moltings (referred to as instars), eventually forming a pupa, which then emerges as the adult moth.
