Weighted Casemaker
A caddisfly that attaches heavy ballast stones to the sides of its case for stability. Larvae are found in fast-flowing stony streams.
Did You Know?
The ballast stones can weigh several times more than the larva itself, preventing displacement by floods.
Japanese Lunar Moth
A beautiful pale green moon moth found in Japan, known as 'o-mizuao.' Features long, elegant tail streamers on the hindwings. Closely related to the Luna moth of North America.
Did You Know?
The long tail streamers on the hindwings create acoustic interference that confuses bat echolocation, helping the moth evade predation.
