[R]Description
Apterous adult: 2 mm long; pale green.

[R]Biology
Originating from Japan, this species was first seen in Switzerland in 1947. Its main host is peach.

[R]Life Cycle
A heteroecious species overwintering in the egg stage at the base of the buds of peach. Migration to Clematis occurs early, in late May to early June; delayed return migration of the sexuparae takes place in October or November.

[R]Damage
- The damage done is very characteristic of this species. Aphids occur on the underside of leaves which undergo severe curling, thus taking on the shape of a cigar. The lamina reddens progressively (*) .
- Certain non-commercial varieties of peach are resistant to infestations of this aphid and those of the peach-potato aphid (Myzus persicae).
