Most hollies have some leaves infested with leaf miner. The damage can be unsightly but has little impact on the plant’s growth or vigour.
Common name Holly leaf-minerScientific name Phytomyza ilicisPlants affected Holly (Ilex species)Main symptoms Yellowish-purple blotches on the upper leaf surfaceMost active All year
Holly leaf miner is a small fly with larvae that cause discoloured blotches by feeding inside holly leaves.
Signs that holly leaf miner has been active include;
Grubs of the holly leaf miner tunnel inside the leaves. There is one generation a year, and the adult flies lay eggs on the new foliage in May to June. When the larvae have completed their feeding in the following spring, they pupate inside the leaf mines.
