Pest description and damage Whiteflies are tiny, pure white, moth-like plant sucking insects. They lay tiny black eggs inserted on the undersides of leaves. The nymphs are yellowish and will also feed by sucking plant sap from the host. Leaves may turn yellow or dry and fall, or leaves may be covered by honeydew followed by the sooty mold fungus. Some whiteflies can transmit viruses. Fuchsias can be severely damaged by high populations of whiteflies.
