Natural Habitat

Vegetation, gardens, woodland edges, and structures near host plants; often found on leaves and stems.

Diet & Feeding

Nymphs typically suck sap from leaves, stems, fruits, or seeds using piercing-sucking mouthparts. Some species also prey on other insects.

Behavior Patterns

Wingless, green nymphs molt through several stages before becoming winged adults; many release a strong odor when disturbed. They are generally slow-moving but may drop or fly away when threatened.

Risks & Benefits

Most are harmless to people, though plant-feeding species can damage crops and garden plants; a few are agricultural pests. Predatory species help suppress caterpillars and other soft-bodied insects.
