Mealybug

Natural Habitat

Found on various host plants, including indoor houseplants, greenhouses, gardens, and agricultural crops in warm, moist environments.

Diet & Feeding

Plant sap (phloem) extracted using piercing-sucking mouthparts.

Behavior Patterns

Mealybugs are often gregarious and move slowly. They secrete a white, waxy, cottony substance for protection against heat and moisture loss. They excrete honeydew, which can lead to sooty mold growth.

Risks & Benefits

Major agricultural and horticultural pests. They weaken plants by draining sap, causing yellowing, leaf drop, and stunted growth. They do not pose a direct health risk to humans but can devastate crops and ornamental plants.
