Diplolepis mayri is a gall inducing insect (Hymenoptera: Cynipidae) causing galls on wild roses (Rosa sp.)

Diploleis mayri is less frequent on rose shrubs than D. rosae.

Galls of D. mayri are multilocular and its chambers have thicker walls than found in D.

These predators may be birds as in the case of other Cynipidae galls: for D. rosae the lesser spotted woodpecker (Picoides minor),[2] for Andricus spp.

One inquiline species, Periclistus brandtii also occurs in both galls.
