Aphids, also known as Greenfly, are mostly monophagous. This means that they will eat only one species of plant. However, some species of Aphid are myxus pwesicae and will eat from many different plants across a variety of families. The aphids lust of plant matter can make them a pest to many horticulturists.
So, in short, Greenfly eat plants.
To be more precise they take in the sap from the plant. Sap is full of sugars, minerals and goodies that the plant would otherwise use to grow. So when this is diverted to make the greenfly grow the plant suffers.
A couple of interesting points: greenfly are a major source of food for ladybirds and also blue-tits ... and ... they don't actually suck, they just insert their needle like mouths into a stem and the pressure in the stem forces the sap into their bodies!

What foods do bees and greenfly get from roses?
Greenfly use their mouthparts to pierce the stems and leaves of the rose and drink the plant's sap which contains sugars and other nutrients.With bees it is a little more complicated. For a single-flowered rose or for a variety where the petals open wide, bees can get to the nectaries and they will take the nectar. For double-flowered roses the nectaries are hidden by the petals, and the bee's proboscis is not long enough to reach them. But, as the greenfly are feeding they will excrete droplets of a sugary liquid called honeydew and the bees sometimes will take this.Generally, it is ants that feed off greenfly honeydew rather than bees.
