Vegetable 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 carunculate and metachromatic. In addition to sap sucking, aphids may carry viral diseases (e.g. Y virus, CMV cucumber mosaic, tomato aspermia, watermelon mosaic, cucumber jaundice), in which case the corresponding symptoms occur.
Adult aphids are 1-4 mm long and their coloring varies according to the species: green, yellow, reddish, brown, brownish-black, greyish-green.
There are both winged and wingless forms.
The nymphs resemble the adults in appearance.
