Atlas Moth Welfare: The World Largest Moth and the Silk Trade

Atlas moths are among the largest moths in the world. Their cocoons are used in small-scale silk production, and wild populations face habitat pressure from deforestation across Southeast Asia.

Key Facts

Atlas moths have wingspans of up to 30 cm — among the largest of any moth species
Adults have no functional mouthparts and cannot eat — they survive only a week or two
Their silk cocoons are used to make small purses in Taiwan and parts of Southeast Asia
Atlas moth caterpillars are large and feed on a range of tropical tree species
Deforestation in Southeast Asia is reducing wild atlas moth populations in some regions

Welfare Considerations

Small-scale atlas moth silk production typically involves boiling pupae to unravel cocoons — a practice that kills the insect at a sensitive developmental stage. Whether pupae experience pain is uncertain, but the practice kills many individuals for limited yield. Wild collection of cocoons also disrupts local populations. Unlike commercial silkworm operations, atlas moth silk is not industrialised, limiting total harm but still warranting consideration of more ethical alternatives.

What You Can Do

Choose plant-based or recycled fabric alternatives to silk
If buying silk products, research whether producers use more humane sericulture methods
Support organisations that work to preserve forest habitat across Southeast Asia
Share information about silk production welfare with others interested in sustainable fashion
