Diplolepis rosae is a gall wasp which causes a gall known as the rose bedeguar gall, robin's pincushion, mossy rose gall, or simply moss gall. The gall develops as a chemically induced distortion of an unopened leaf axillary or terminal bud, mostly on field rose (Rosa arvensis) or dog rose (Rosa canina) shrubs.
