White Fly Trialeurodes vaporariorum, Bemisia tabaci
Whiteflies are not true flies, but belong to the order Hemiptera (true bugs). Together with aphids and scale insects, they belong to the division Sternorrhyncha. The whiteflies form the family Aleyrodidae. The most common species are the greenhouse whitefly, Trialeurodes vaporariorum, and the tobacco whitefly, Bemisia tabaci. Both are widespread, and are broadly comparable in outline.
