Mealybug

Natural Habitat

Warm, moist environments; typically found on the undersides of leaves, stems, and roots of indoor and outdoor plants.

Diet & Feeding

Plant sap; they are fluid-feeders that use piercing-sucking mouthparts to extract nutrients from host plants.

Behavior Patterns

They are slow-moving insects that secret a white, waxy, cotton-like coating for protection. They often cluster in hidden areas of plants and excrete honey-dew, which can lead to sooty mold growth.

Risks & Benefits

Significant agricultural and horticultural pests that cause leaf yellowing, stunted growth, and plant death. They offer no direct benefits to humans and are difficult to eradicate once established.
