Dock aphid (Aphis rumicis)?

Observation - Dock aphid (Aphis rumicis)? - UK and Ireland. Description: Small (about 2mm) coal-black aphids feeding on dock (Rumex). Longitudinally rolled and crumpled lea

Small (about 2mm) coal-black aphids feeding on dock (Rumex). Longitudinally rolled and crumpled leaves of dock (photos 2 and 3) indicate developing colonies of dock aphid (this also distinguishes Aphis rumicis from Aphis fabae which does not roll the leaves). Later on they move up stems and into the inflorescences (photos 1 and 5). Aphis rumicis is usually attended by ants (see Lasius in photos 2 - 4). The ladybird in photo 6 was happily munching it's way through quite a number!
