Water-lily Reed Beetle
A metallic coppery-bronze aquatic beetle with longitudinal ridges on the elytra. Adults sit on floating leaves of pondweeds and bur-reeds in still or slow-flowing water.
Did You Know?
Larvae construct a silken cocoon underwater attached to plant roots, filling it with air obtained from the plant's tissues for pupation.
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.
