Cairns Birdwing Butterfly (Ornithoptera priamus) Lifecycle sequence part 3 - Caterpillar

The birdwing butterfly exhibits unique behavior by leaving its food plant before pupating to avoid risks. It uses two methods of attachment: securing itself to a stem with its tail and weaving a silk girdle. This girdle, fitting snugly between body segments, supports the pupa's weight. Additionally, the birdwing's chemical defenses protect it from predators.

How does the birdwing caterpillar protect itself from predators?

• By hiding under leaves
