See this bug in the Encyclopedia

Natural Habitat

Found on woody plants and trees, particularly in gardens, orchards, and forests where their host plants grow.

Diet & Feeding

Plant sap, feeding exclusively on the phloem of specific host plants using piercing-sucking mouthparts.

Behavior Patterns

Many species are host-specific and jump when disturbed. Females lay eggs on plant buds or leaves, and nymphs often produce waxy secretions or protective gall structures.

Risks & Benefits

Can be significant agricultural and forestry pests due to feeding damage, stunting growth, and transmitting plant pathogens (such as bacteria causing citrus greening), though they serve as a food source for beneficial predators like ladybugs.
