Summary
Heliothinae is a small yet diverse subfamily of moths known for its agricultural pest species and adaptation to warm, dry habitats.
Physical Characteristics
Forewings often have distinctive patterns or colors; body size varies but is generally medium-sized for moths.
Identification Tips
Look for characteristic wing shapes and patterns, especially in the forewings; presence of specific larval host plants may aid in identification.
Habitat
Thrives in hot, dry regions; commonly found in seasonally-arid tropics and subtropics.
Distribution
Cosmopolitan subfamily with a presence in Australia, sections of Asia, the southwestern United States, and Africa.
Diet
Larvae may be specialist feeders on limited ranges of plants or generalists feeding on various host plants.
Life Cycle
The life cycle includes egg, larval (caterpillar), pupal, and adult stages, with significant variation in duration based on species and environmental conditions.
Reproduction
Species exhibit different reproductive strategies; generally, oviposition occurs on or near host plants to maximize survival of larvae.
Predators
Natural predators include birds, other insects, and parasitoids that target the larvae and adults.
Ecosystem Role
Plays a significant role as herbivores in ecosystems, impacting plant communities and serving as prey for higher trophic levels.
Economic Impact
Includes several economically significant agricultural pests which affect crops, such as Helicoverpa armigera and Helicoverpa zea.
Collecting Methods
- Netting adults at light traps
- Surveillance of host plants for larvae
Preservation Methods
- Drying
- Pinning
- Ethanol preservation
Evolution
Extensively studied regarding phylogeny and host plant evolution, showing significant diversity and adaptation.
