The apterae are dark brown and shiny. The siphunculi and antennae are dark while cauda and antennal segment III are pale yellow. Siphunculi dark at the base and apex, middle portion relatively pale. The alatae are completely dark brown. The aphids are found on all parts of the plants. The aphid drops down to the ground on disturbance. This aphid is sometimes found in association with Hyperomyzus carduellinus.

Antennae almost equal to or 1.05 times as long as body. Segment three shorter than segment IV and V put together. Siphunculi 1.7 times as long as cauda. Cauda with 20-30 hairs.
