Nymphs are smaller than the wingless adult but similar in shape and color.
The melon aphid has a wide host range. They have been found on all the cucurbits, bean, pea, eggplant, okra, spinach, tomato and cotton. There are certainly other hosts not reported. Congregating on lower leaf surfaces, they pierce the plant and suck sap. Leaves curl downward and pucker.
