The wingless aphids are medium-sized to rather large, broadly spindle-shaped, shiny, and pale to dark green or deep pink to red-brown or magenta, with shiny black head. Antennae and legs bicoloured, yellow and black.
They bear live young as opposed to laying eggs.
As the name suggests the aphid is to be found on various types of rose (Rosaceae sp) and mainly colonises tender flower buds, young shoots and lower surface of young leaves.
