Common Rose Aphid (Macrosiphon rosae) Family Aphididae

Rose Aphids can be found on the roses in early spring but a spray of soapy liquid will control them instead of pesticides.
Their natural enemies are ladybirds, hoverflies and some small birds.

They are easily identified by their knees, antennae and very long horns on abdomen being black. In this photograph you can see ladybird larva too.

They range from pale pink to reddish brown in color and are found in winged form.
