The leafhopper family Cicadellidae (Hemiptera: Auchenorrhyncha) is plant feeders, with mouthparts adapted for sucking. Almost of the them cause injuries of destruction to plants, including fruit trees and grain crops, and can be vectors of plant diseases. Therefor, Cicadellidae is one of the most important pests in the world. However, their identifications are very difficult because of small size and morphological similarities, and their exact biological information such as host plants, life cycle and distribution are not clear for most species. So, we provide and integrated biological database that present accurate diagnostic methods and ecological infromation.
