Phylloxera stanfordiana
Phylloxera stanfordiana is a species of phylloxeran insect in the family Phylloxeridae, order Hemiptera. It is closely related to aphids and shares their soft-bodied morphology and plant-feeding habits. The species was described by Ferris in 1919. Like other phylloxerans, it is known to induce gall formation on host plants through its feeding activity. The specific epithet 'stanfordiana' refers to Stanford University, where the type specimen was collected in 1904.
