Mealybug (likely a species of mealybug, given the appearance)
Scientific Name: Various species within the Pseudococcidae family (e.g., Planococcus citri, Dysmicoccus brevipes)
Order & Family: Order: Hemiptera, Family: Pseudococcidae
Size: Typically 1-6 mm (.04 - .24 inches) in length, adult females are often larger and more easily visible.
Natural Habitat
Mealybugs are common agricultural and greenhouse pests. They can be found on a wide variety of plants, indoors (houseplants) and outdoors, in warm and humid conditions. They prefer sheltered locations on plants.
Diet & Feeding
Mealybugs are sap-sucking insects, feeding on plant sap by inserting their stylets (mouthparts) into the phloem vessels of plants. They excrete a sugary substance called honeydew.
Behavior Patterns
Mealybugs are typically slow-moving and often appear sessile, especially the adult females. They produce a white, cottony, waxy coating that protects them and their eggs. They tend to cluster in protected areas on plants, such as leaf axils and undersides of leaves. Reproduction can be sexual or parthenogenetic (without fertilization).
Risks & Benefits
Risks: Mealybugs are significant pests of agricultural crops, ornamental plants, and houseplants. Their feeding can cause wilting, yellowing, leaf drop, stunted growth, and even plant death. The honeydew they excrete can lead to the growth of sooty mold, which blocks photosynthesis and further reduces plant vigor. Benefits: No significant benefits are associated with mealybugs; they are primarily considered pests.
