Honeydew producers that feed on plant sap using piercing-sucking mouthparts.

Behavior Patterns

They produce a characteristic waxy, white, 'woolly' filaments that cover their bodies for protection against predators and desiccation. They are active during the growing season and often aggregate in large groups.

Risks & Benefits

Generally harmless to humans but can be a minor agricultural and garden pest. They cause aesthetic damage to plants, leaf curling, and the sticky honeydew they secrete can lead to the growth of black sooty mold.
