[R]Description
Adult: 2-2.2 mm long; body rectangular, dull and very dark green; antennae short; siphunculi small and swollen (*) .

[R]Biology
- This aphid develops on the stems and the upper surface of leaves of maize (*) and sorghum, and occasionally on barley and rye.
- A common species in countries with hot climates, thus occurring in France in the Mediterranean region only, where maize is cultivated. Elsewhere, the bird-cherry aphid (Rhopalosiphum padi) is far more common.

[R]Life Cycle
An anholocyclic aphid reproducing parthenogenetically only.

[R]Damage
Affected leaves curl longitudinally and aphids excrete vast quantities of honeydew on which sooty moulds develop.
