Lymantriinae is a subfamily of moths within the family Erebidae. These moths are commonly known as tussock moths and are characterized by their hairy caterpillars, which often have distinctive tufts or "tussocks." They are found in various habitats around the world, including forests and grasslands. The adult moths typically have robust bodies and broad wings, with many species displaying striking patterns and colors. Lymantriinae caterpillars are known for their feeding habits, often consuming leaves from a wide range of plants, which can sometimes lead to significant defoliation in forests.
