Mealybug
Pseudococcidae (Family name)
- Order & Family
- Order: Hemiptera, Family: Pseudococcidae
- Size
- 1 to 4 mm (0.04 to 0.16 inches) in length.
Natural Habitat
Typically found on the undersides of leaves, stems, and crevices of various host plants, including fruit trees, houseplants, and garden ornamentals.
Diet & Feeding
Herbivorous; they use piercing-sucking mouthparts to feed on plant sap (phloem), often excreting a sugary liquid known as honeydew.
Behavior Patterns
Mealybugs are slow-moving and often secrete a white, waxy, cotton-like substance for protection against heat and moisture loss. They are known for forming colonies and can reproduce rapidly in warm, humid conditions.
Risks & Benefits
They are serious agricultural and horticultural pests that cause stunted growth, yellowing, and leaf drop. The honeydew they excrete promotes the growth of sooty mold, which blocks photosynthesis. They generally pose no direct risk to human health.
