Thanks so much, Toko I did some googling to find out a bit more -- fascinating!
I also had a closer look at the goggas on the rose and I think that they are some sort of Japanese beetle, which I think are a typical rose infestation? I've cropped the photo some more, to show them better. What do you think .....
