Diplolepis rosae
Found on Rosa canina (dog rose).
It develops as a chemically induced distortion of an unopened leaf axillary or terminal buds mostly on Field Rose (Rosa arvensis) or Dog rose (Rosa canina) shrubs, caused by the parthenogenetic hymenopteran gall wasp Diplolepis rosae. Diplolepis lay up to sixty eggs within each leaf buds (source: wikipedia.org).
