The Gypsy Moth (*Lymantria dispar*) is an invasive insect native to Europe and Asia. It is known for its destructive caterpillars, which feed on the leaves of various trees, particularly oak, birch, and maple. The moth's life cycle includes several stages: egg, larva (caterpillar), pupa, and adult moth. Adult Gypsy Moths are typically brown with distinctive markings, and females are larger than males. They can produce hundreds of eggs, leading to rapid population growth. Control measures often include monitoring, biological control, and insecticides to protect forests and ecosystems from their damaging effects.
