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.
