Mealybug

Natural Habitat

Found on a wide variety of plants, often in warm, moist climates, but also common on houseplants indoors year-round. They tend to congregate in leaf axils (where leaves join the stem) and on the undersides of leaves.

Diet & Feeding

They feed on plant sap (phloem) by piercing plant tissue with their mouthparts given their classification as sucking insects.

Behavior Patterns

Mealybugs are slow-moving insects that secrete a powdery wax coating for protection, which gives them a 'mealy' or cottony appearance. They tend to cluster together in hidden areas of plants. As they feed, they excrete a sticky substance called honeydew, which can attract ants and promote the growth of sooty mold.

Risks & Benefits

Risks: They are considered agricultural and horticultural pests. Heavy infestations can weaken plants, cause yellowing and leaf drop, and stunt growth. The honeydew they produce leads to fungal growth (sooty mold). Benefits: They produce honeydew which is a food source for some ants and other insects, and are prey for ladybugs and lacewings.
