Natural Habitat

Found on the leaves of host plants, including morning glories, sweet potatoes, and various garden shrubs.

Diet & Feeding

Herbivorous; they feed on the foliage of their host plants, often creating characteristic holes in the leaves.

Behavior Patterns

They are known for their protective, transparent margins of the elytra (wing covers), which give them a turtle-like appearance. Some species can rapidly change color when disturbed or during mating.

Risks & Benefits

Generally considered a minor garden pest due to foliage consumption, but they provide aesthetic interest and serve as a food source for birds and predatory insects.
