Dasineura aparines

The larvae of the midge Dasineura aparines cause galls on Cleavers causing the buds and adjacent stems to become thickened, hairy and fleshy, sometimes grouped into a rosette like mass at the tops of the stems.

Cecidophyes rouhollahi

The Gall Mite Cecidophyes rouhollahi causes galls to form distorting the leaves of Goosegrass (Galium aparine). These galls were previously thought to be caused by Cecidophyes galii but this has now been disproved, and there is no evidence at present that C. galii causes galls in Britain.
