Natural Habitat

Warm, moist environments; commonly found on indoor houseplants, in greenhouses, and on many outdoor agricultural crops.

Diet & Feeding

Herbivorous; they pierce plant tissues and suck out sap using specialized mouthparts called stylets.

Behavior Patterns

They are slow-moving and often cluster in protected areas of plants, like leaf axils. They excrete a waxy, white coating for protection and produce honeydew, a sticky substance that can lead to sooty mold growth.

Risks & Benefits

Generally considered pests; they can weaken or kill plants by draining sap and transmitting plant diseases. They offer no direct benefits to humans and are difficult to control due to their protective wax.
