gall
Apterae 3-4 mm, with long hairs and short siphunculi. No host plant alternation, sometimes attended by ants; on the young shoots, petioles, underside of the leaves and in the inflorescence. The aphids cause suction damage (disfiguring, growth disturbance) of the inflorescence and young foliage. During the hottest period in summer groups of young larvae enter into aestivation.
host plants
Sapindaceae, monophagous
Acer campestre, granatense, negundo, opalus, pseudoplatanus, saccharum.
A pseudoplatanus is the normal host plant; not, or in very small numbers, on A. platanoides.
synonyms
Chaetophoria acericola.
