Similar to: Other aphid species.
Damage: Sucks sap, large numbers cause malformation of new growth including flower buds. Indirectly damages plants by transmission of a large number of viruses including several mosaics. Produce honeydew, encouraging sooty mould growth, which reduces plant vigour. Wide host range, very common.
- Egg: Black, shiny, but rarely laid, mainly produces live young.
- Immatures: Resemble adult. White papery skins are shed as they grow and are often found on the leaves below and on buds.
- Adult: Light to dark green or pink, red eyes. Three dark lines run down back, small body. Winged female with central black patch on the upper surface of the abdomen and a dark head and thorax. Cornicles have distinct dark tips.
