Phyllaphis is a genus of woolly aphids in the family Aphididae, established by Koch in 1856. The genus comprises at least four described species, with Phyllaphis fagi and P. grandifoliae commonly known as woolly beech aphids. Species in this genus are associated with beech trees (Fagus spp.) and exhibit complex life cycles with multiple generations per growing season. The genus has been subject to taxonomic revision, with some species historically placed in related genera such as Tamalia.
