Summary
Lymantria is a genus of tussock moths in the family Erebidae, characterized by distinct male and female morphology and primarily composed of species found in Eurasia. The Gypsy Moth, Lymantria dispar, is the only species present in North America and is known for its invasive nature and significant ecological and economic impact.
Physical Characteristics
Males typically have a wingspan of 38 mm, while females have a larger wingspan. Male palpi are porrect and hairy, with long-branched antennae. Female antennae are serrate, and the wings can be fully developed, partially reduced, or completely reduced to scales.
Identification Tips
Distinguish males by their hairy, porrect palpi and branched antennae; females can be identified by their serrate antennae and variation in wing development.
Habitat
Widely distributed throughout Europe, Japan, India, Sri Lanka, Myanmar, Java, and Celebes.
Distribution
North America (introduced species Lymantria dispar); native species in Eurasia.
Diet
Larvae are known to feed on a variety of deciduous trees.
Life Cycle
Life cycle includes egg, larva, pupa, and adult stages, typical of moths.
Reproduction
Reproduction occurs sexually with females often laying eggs in masses covered with a protective layer.
Ecosystem Role
Act as herbivores, impacting tree populations and serving as prey for various predators.
Economic Impact
Some species, like Lymantria dispar (Gypsy Moth), are known to cause significant defoliation and economic losses in forestry.
