Periphyllus testudinaceus: aestivating larva

aestivating larva (from Hille Ris Lambers, 1947b)

gall

the aptera is dirty green to dark brown, always with a number of transversal rows of black sclerites. No host plant alternation, often attended by ants. The aphids cause suction damage (disfiguring, growth disturbance) to the inflorescence and young foliage. During the warmest period of the summer the larvae go through an aestivation period; they are almost immobile and have an unique appearance.

hostplants

Sapindaceae, almost monophagous

Acer buergerianum, campestre, davidii, davidii, granatense, japonicum, monspessulanum, negundo, oblongum, opalus, palmatum, pensylvanicum, platanoides, pseudoplatanum, rubrum, saccharinum, saccharum, tataricum & subsp. ginnala.

The most common host plant is A. campestre; rarely also on Aesculus hippocastanum, x neglecta, pavia and Xanthoceras sorbifolium.

synonyms

Periphyllus villosus (Hartig, 1841); P. testudinatus (Thornton, 1852).
