Mealybug

Natural Habitat

Warm, humid climates; found on plant leaves, stems, and roots in gardens, greenhouses, and on houseplants.

Diet & Feeding

Plant sap (phloem feeders) from a wide variety of ornamental plants, fruit trees, and vegetables.

Behavior Patterns

They secrete a powdery wax layer for protection, giving them a cottony appearance. They tend to cluster in protected areas of plants like leaf axils. They produce honeydew, which attracts ants and promotes sooty mold growth.

Risks & Benefits

Risks: Major agricultural and horticultural pest; they weaken plants, cause yellowing and leaf drop, and can transmit plant viruses. Benefits: None significant for humans, though they serve as food for ladybugs and lacewings.
