Mealybug

Natural Habitat

Found worldwide in warm, moist climates; commonly infests indoor houseplants, greenhouses, and outdoor crops like citrus, grapes, and ornamentals.

Diet & Feeding

Plant sap (phloem feeders); they use piercing-sucking mouthparts to extract nutrients from stems, leaves, and roots.

Behavior Patterns

They secrete a powdery white wax as a protective coating, giving them a cottony appearance. They tend to cluster in protected areas of plants like leaf axils and undersides. They produce honeydew, which can attract ants and promote sooty mold growth.

Risks & Benefits

Risks: Significant agricultural and horticultural pests; cause stunted growth, yellowing leaves, and can spread plant viruses. Benefits: None significant generally, though they serve as prey for certain beneficial insects (ladybugs, lacewings).
