Aphids species each exhibit several biologically and morphologically different forms

Aphid species can exhibit as many as 12 different forms, or morphs, during the course of their seasonal life-cycle. AphID only considers adult female viviparae, apterous and alate. It does not treat males, oviparae, immatures, or any number of other specialized morphs. Before using AphID, it is important to confirm that the unidentified specimen is an adult female vivipara, and NOT an immature, an ovipara, or a male.
