Diplolepis centifoliae

Galls are small, spherical with a smooth surface, single chambered and scattered over the surface
of leaflets. They are yellowish green when immature then turn either dark green to
purplish red when mature and finally brown once dry. They are found on both the adaxial
and abaxial surfaces of leaflets and are easily dislodged because the point of attachment is
narrow.
