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.

Colorado Leaf Beetle

A close relative of the Colorado potato beetle with similar striped elytra but alternating dark and light brown stripes rather than black and yellow. It feeds on native horsenettle.

💡

Did You Know?

Unlike its notorious relative the Colorado potato beetle, this species has not adapted to crop plants and remains relatively harmless to agriculture.
