Fold-Gall Aphid (Tamalia coweni)

This aphid induces two kinds of galls: one, a common and widespread fold gall along the margins or midribs of leaves, occurring on many species of glabrous-leaved manzanitas; and the second, an uncommon convoluted swelling or baglike structure on the inflorescences of manzanitas.

[UPDATE: Please read Gallformers ID Notes above for a 2023 taxon split that narrows the host list for this gall.]
