Table 1. Some features of the biology, host associations and life cycles of Aphidoidea. The bracketed figures are total numbers of genera/total numbers of species : numbers of genera known to live on trees/numbers of species known to live on trees. The classification follows that used by Remaudière and Remaudière (1997), with the revision of family names proposed by Nieto Nafrìa et al. (1998), rather than that of Heie & Wegierek (2009), which raises many subfamilies to family level. Table 3 compares the two classifications.
