Contarinia tiliarum


    Contarinia tiliarum is a midge that causes galls to form on Lime. The galls are hard globular swellings, 2 to 15 mm across which occur on the petiole, flower stalk or young stem and occasionally extending into the midrib of the leaf or the main vein of the bracteole. It is pale coloured, becoming green and often reddened. It may have one or many chambers each containing a lemon yellow larva.
