Summary
Lymantriinae, or tussock moths, is a subfamily of moths known for their distinctive hairy larvae. They are important forest defoliators and have a wide distribution, with species present on every continent except Antarctica. The adult moths typically possess muted colors and may have reduced wings.
Physical Characteristics
Medium sized moths with wingspans ranging from 1.5 to 6.7 cm; females are usually larger than males. Moths typically have muted colors (brown, gray, white) and are hairy. Some females are flightless or have reduced wings. Larvae are hairy with bristles and can have tufts of hair on their bodies.
Identification Tips
Look for the distinctive tufts of hair on caterpillars which suggest the common name 'tussock moths'. Adult moths may exhibit vaporous flight patterns. Increased size and hairiness in females can help in identification.
Habitat
Found in forests, woodlands, shrubs, and other vegetation where host plants are available. They are particularly concentrated in sub-Saharan Africa, India, Southeast Asia, and South America.
Distribution
Lymantriinae species are found on all continents except Antarctica, with significant concentrations in sub-Saharan Africa, India, Southeast Asia, and South America, notably Madagascar.
Diet
Most larvae feed on trees and shrubs, but some are known to feed on vines, herbs, grasses, and lichens.
Life Cycle
The lifecycle includes egg, larval (caterpillar), pupal, and adult stages. Larvae are hairy and often defensive, incorporating hairs into their cocoons and camouflaging their eggs.
Reproduction
Females often collect and store hairs to camouflage eggs, which may also be covered with a frothy substance or other materials to protect them during development.
Predators
Predators largely include birds and other insectivorous animals that feed on caterpillars and adult moths.
Ecosystem Role
Lymantriinae are important in ecosystems as herbivores and some species are significant defoliators of forest trees, playing a role in shaping vegetation dynamics.
Economic Impact
Several species can be agricultural pests, as they defoliate crops and forest trees, potentially leading to economic losses in forestry and agriculture.
Health Concerns
Some species have urticating hairs that can cause painful reactions upon contact with skin.
Collecting Methods
- Light trapping
- Netting during flight periods
- Visual searches on host plants
Preservation Methods
- Pinning
- Drying in an insect drawer
- Preserving in ethanol for larvae
Evolution
Lymantriinae was formerly classified as its own family, Lymantriidae, but was reclassified as a subfamily of Erebidae in 2010 following phylogenetic studies.
Misconceptions
Some assume that all tussock moths are harmful to humans due to their urticating hairs; however, not all species pose a health risk.
