They are able to "jump" up to four times their body length high while making their loud click. This is a very effective evasive maneuver when they are threatened by a predator. It has a spine tucked into a groove in its back poststernum. When it flexes its back, the spine comes under tension, then pops out like you snap your fingers, creating both the click and the jump
This video demonstrates the "click," speed and flight characteristics.
The adult's food consists of plant juices and nectar. It has prominent eye spots which are actually colored scales like on a butterfly wing. Presumably these false eyes are threatening to some potential predators.
