Range & Status
Hemiptera: Aphididae; local.
VC1: SW87 Porthcothan in 2008, a first record for Cornwall.
Habitat & Ecology
Associated species: Mugwort Artemisia vulgaris . Gall causes some or most of the leaves to be thickened and curled together, especially towards the shoot tip; these are often pinkish purple and aphids are present under the leaves. The host plant is distributed all over Cornwall, and it seems strange that these aphids have not previously been recorded.
