The white flies flying around are small, sap-sucking insects called whiteflies. They are not true flies but are related to aphids and mealybugs. Whiteflies are tiny with yellowish bodies and wings covered in a mealy white wax, giving them a white appearance. They usually hover around plants, often on the undersides of leaves, and can fly short distances when disturbed. These insects feed on plant sap, which can cause yellowing, drying, or dropping of leaves. They also excrete a sugary substance called honeydew, which can lead to sticky leaves and promote sooty mold growth. Whitefly populations can build up quickly, especially in warm weather or when natural predators are disrupted. They are common pests in gardens, greenhouses, and on houseplants and can be difficult to control once established.
