Diplolepis rose (Robin's Pin-Cushion Gall)

Observation - Diplolepis rose (Robin's Pin-Cushion Gall) - UK and Ireland. Description:

Rosa canina is intertwined with the Blackberry but the Gall seemed to be growing on the Blackberry....or so I thought, but as Chris Brooks has pointed out, this Gall Wasp is species-specific so it cannot be growing out of the Blackberry as it appears, but will be attached to the Rose branch.
