   🚨 ARTHROPOD OF THE DAY 🚨
   
   Whiteflies are soft-bodied, winged insects closely related to aphids and mealybugs. Whiteflies are not true flies although they look fly-like. They actually belong to the same order of insects as scales, aphids, and mealybugs: the order Homoptera.
   
   Whitefly adults resemble tiny moths and are covered with a whitish powder. Species identification can be made by examining the wing markings. The first instar nymphs resemble scales, but they become a transparent yellow-green and settle once they reach the second and third instar stages.
   
   Whiteflies are “true bugs” (Hemiptera) that feed on plant sap, much like aphids. Adults are very small (1/16 - 1/10 inch) with powdery white wings. Females lay eggs directly on the undersides of plant leaves. The eggs hatch into tiny “crawlers” that walk a short distance before settling at a feeding location. These nymphs lose their ability walk, and remain in the same location for the rest of their development until they pupate and emerge as winged adults (Figure 1). The entire whitefly life cycle takes about 3 weeks under favorable conditions, allowing populations to build quickly. Whiteflies do not have a dormant stage that can withstand freezing temperatures. In climates that have winter freezes, such as Kentucky, whiteflies are year-round pests only in greenhouses.
