Natural Habitat

Gardens, agricultural fields, forests, and landscaped areas where aphids and other small pests are present. They are often found on leaves, stems, and tree trunks.

Diet & Feeding

Carnivorous predator. They primarily feed on aphids (leading to the nickname 'Aphid Lion'), mites, mealybugs, whiteflies, and insect eggs. They are voracious eaters.

Behavior Patterns

The most notable behavior is camouflage. The larvae collect exoskeletons of their prey, pieces of lichen, moss, and other debris, sticking them to hooked bristles on their back to create a protective shield. This hides them from predators like birds and larger insects.

Risks & Benefits

Benefits: Highly beneficial to gardeners and farmers as a natural biological control agent against soft-bodied plant pests like aphids. Risks: Generally harmless to humans, though they can deliver a very mild, non-venomous bite if handled roughly, which feels like a small pinch.
