gall

when the galls are ripe, they get a star-like opening at the top, releasing the winged aphids that will colonize the secondary host plants.

host plants

Ulmaceae, monophagous

Ulmus glabra, x hollandica, laevis, minor, procera.


on Lamiaceae, secondary host plants

gall

aphids live on the roots.

host plants

Lamiaceae, oligophagous

Galeopsis; Mentha x piperita, suaveolens; Origanum; Stachys; Thymus.

synonyms

Pemphigus pallidus.

notes

In Central Europe the species can live permanently without host plant alternation on the secondary host plants (Heie, 1980). Perhaps this explains the rarity of the gall.
