See this bug in the Encyclopedia

Natural Habitat

Found worldwide in gardens, forests, agricultural fields, and occasionally indoors on houseplants; generally wherever aphids are present.

Diet & Feeding

Carnivorous predator; primarily feeds on aphids, mites, thrips, mealybugs, whiteflies, and insect eggs.

Behavior Patterns

These larvae create a camouflage shield by attaching debris (insect exoskeletons, plant matter, lichen) to bristles on their backs. This mobile 'trash pile' protects them from predators like birds and ants.

Risks & Benefits

Benefits: highly beneficial for pest control in gardens as voracious aphid eaters. Risks: harmless to humans and structures, though they can deliver a minor, non-venomous bite if handled roughly.
