Potato Aphids are usually found on the lower surface of the leaf, where they form colonies. A characteristic feature is the production of honeydew. In severe infestations the leaves become bumpy and metachromatic. In addition to sap sucking, aphids may carry viruses (e.g. leaf curl virus, A, M and Y), in which case the leaves show the corresponding symptoms.
Aphid adults are 1-4 mm long and their coloration varies depending on the species: green, yellow, reddish, brown or brownish-black. There are both winged and wingless forms. The nymphs resemble the adults in appearance.
