Natural Habitat

Arid areas and rocky outcrops (koppies) across South Africa, commonly found in garden shrubs and indigenous vegetation.

Diet & Feeding

Herbivorous; they feed on a wide variety of plants, often preferring those containing toxic compounds like Milkweed.

Behavior Patterns

Sluggish and flightless movemets; they are known for a defense mechanism where they expel a smelly, toxic foam from their thoracic joints when threatened. The bright colors serve as aposematic (warning) coloration.

Risks & Benefits

They are toxic if ingested by predators or humans due to the chemicals sequestered from their diet. They do not bite or sting but can cause skin irritation; ecologically, they serve as a food source for specialized predators and help regulate plant growth.
