Robin's pincushions everywhere

Robin’s pincushions, a gall which affects wild roses. In the past, I don’t remember ever seeing more than one or perhaps two of these brightly coloured growths on a single briar. This year, multiple infestations seem common. These were all on a single bush in the Barley Field blackthorn hedge – I gave up counting when I got to twenty.
