Apterae 2-3 mm. Head dark bluish grey, the rest of the body tender green, around the siphunculi and between them olive-green, the dorsum with whitish grey wax-dust which does not cover very fine lines between the tergites, transversally spindle-shaped, sometimes coalescing intersegmental spots along the spine and narrower, similar pleural spots. Ventrally faintly powdered. Eyes bright red to dark red. Antennae black. Siphunculi black or with green, transparent base, the cauda rather like the base of the siphunculi. Legs either almost completely black or with the middle part of the tibiae and the basal half of the femora paler and more or less transparent. Aphids mainly in the inflorescence, but also at the undersides of the higher and lower leaves.
