Mealybug

Natural Habitat

Found worldwide in warmer climates; commonly inhabits greenhouses, indoor plants, and outdoor vegetation in sheltered areas. They thrive on the soft tissues of plants, such as leaf axils and undersides of leaves.

Diet & Feeding

Sap-suckers; they feed on plant phloem sap, excreting sticky honeydew as a byproduct.

Behavior Patterns

Mealybugs are often immobile or slow-moving once they find a feeding spot. They congregate in white, cottony masses for protection. They reproduce rapidly, with females laying eggs in fuzzy ovisacs.

Risks & Benefits

Risks: Major agricultural and horticultural pests. They weaken plants by draining sap, cause yellowing/wilting, and excrete honeydew that promotes sooty mold growth. Benefits: Some species are prey for beneficial insects like lady beetles and lacewings.
