Aphis ilicis
The Holly Aphid (Aphis ilicis) lives in dense colonies on young shoots and undersides of young leaves of Holly. Attacked leaves curl towards their undersides. Later in the year, when the leaves have matured, aphids can be found colonizing the berry petioles. It is rare to find any species other than Aphis ilicis on Holly. Aphis ilicis apterae are dark olive-brown, reddish-brown or greyish-brown.
Holly Leaf Miner
The larvae of the Agromyzid fly Phytomyza ilicis mine the leaves of Holly producing a characteristic but irregular upper surface linear-blotch mine.
Holly Parachute
This tiny fungus appears on the dead leaves of Holly. To 15 mm with a thin, wiry red stem and a very small off-white cap (2-6mm). Both cap and stems are covered in projecting hairs.
Microthyrium ciliatum
The fruit bodies of the fungus Microthyrium ciliatum are dark brown to blackish, circular, one cell thick, with central ostioles for spore release. Under the microscope they appear as a series of radiating cells, evenly coloured. They rest on the surface of their host with hyphae holding them in place.
Phacidium lauri
The round black pustules of the fungus Phacidium lauri are found on both surfaces of dead Holly leaves.
Holly Speckle
The dark speckling of the Holly Speckle fungus (Trochila ilicina) occurs only on the upper side of dead holly leaves.
