Diplolepis spinosissimae


    The larvae of the gall wasp cause Diplolepis spinosissimae cause galls to form on various rose species, being most frequent on Rosa spinosissima, also found on R. caesia, canina, rubiginosa etc. The galls are smooth, reddish-green, ovoid in shape and may occur on the leaf petiole or protruding from both sides of the leaf but quite often the galls coalesce.  Each gall contains a single white larva.
