Dock Aphid - Aphis rumicis
The wingless form has a length of 2 to 2.7 mm and is black to very dark greenish-brown. The winged form is also mainly black in colour.
It is similar to another Dock feeder Aphis fabae but that species does not cause the leaf edges of Dock to curl.
Feeds mainly on Dock causing the leaves to roll or crumple before later in the year moving up stems and into the inflorescences.
Summer and autumn.
Distribution and status in Britain are difficult to gauge as the species is poorly recorded.
Status in Leicestershire and Rutland not known.
