Witch-hazel Cone Gall Aphid
Hormaphis hamamelidis
The witch-hazel cone gall aphid (Hormaphis hamamelidis) is a minuscule insect, a member of the aphid superfamily, whose presence on a witch-hazel plant is easily recognizable by a red conical gall structure. This gall, rich in nutrients, provides both food and shelter for the female aphid.
