Adults (1/16 inch long) are moth-like insects with powdery white wings and short antennae. They are easily recognized and often found near the tops of plants or on stem ends.
Young nymphs overwinter on the leaves of host plants. In late spring adult females deposit 200-400 eggs in circular clusters on the undersides of upper leaves.
Whiteflies feed on a wide variety of plants, including ornamental flowers and warm-season vegetables like tomatoes, eggplant, peppers, and okra. They can also be found feeding on cucumber, sweet potatoes, and squash.
