aestivating larva (from Hille Ris Lambers, 1947b)

gall

no host plant alternation, not attended by ants. The aphids live at the underside of the leaves, on petioles and on very young shoots; they cause suction damage (disfiguring, growth disturbance) of the inflorescence and young foliage.
During high summer the larvae pass through an aestivation period. They then are long-hairy, and sit immobile in large groups, the head directed towards the centre of the group.

host plants

Sapindaceae, monophagous

Acer platanoides.
