Silk Moth

The fully domesticated moth used in sericulture for over 5,000 years. Completely dependent on humans — adults cannot fly and larvae depend on hand-feeding mulberry leaves.

💡

Did You Know?

The silk moth is so domesticated after 5,000 years of selective breeding that adults can no longer fly and caterpillars will starve rather than eat anything but mulberry leaves.

Willow Bean-Gall Sawfly

A tiny sawfly that induces distinctive bean-shaped galls on the leaves of various willow species. Each gall contains a single larva feeding on internal gall tissue.

💡

Did You Know?

The gall-inducing chemicals secreted by the larva redirect the plant's growth to create a nutrient-rich chamber specifically for the larva's benefit.
