Pemphigus tartareus
Pemphigus tartareus is a North American aphid species in the family Aphididae, described by Hottes and Frison in 1931. It belongs to the genus Pemphigus, which comprises root-feeding aphids often associated with gall formation or subterranean development on host plants. The species has been historically confused with other root-infesting aphids in agricultural and horticultural contexts, particularly in discussions of "root aphid" pests.
