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.
