Greenfly on a rose bud

I accidentally knocked a little sprig of rose buds from a rose when I was dead-heading it the other day, so I brought it in and put it in a little vase.
I noticed this evening that it has greenfly on it. Another job for C tomorrow then - sort out the greenfly.
If you're wondering what the red item is, it's one of those old-fashioned-looking radios, and you can just make out the stitching on it.  I balanced the bud on the radio under a worktop light.
