The witch-hazel cone gall aphid (''Hormaphis hamamelidis'') is a minuscule insect, a member of the Aphid, aphid superfamily, whose presence on a witch-hazel (''Hamamelis virginiana'') plant is easily recognizable by a conical gall structure. The gall is green at first, then turns bright red. This gall, rich in nutrients, provides both food and shelter for the female aphid. ''H. hamamelidis'' have three generations per year, each with a different part in the life cycle. At the start of spring, females or ''stem mothers'' crawl to witch-hazel leaf buds. As the leaf grows, the aphid injects it with a substance, possibly an enzyme or hormone, that causes that the galls to form around her. Once inside her gall, the stem mother reproduces Parthenogenesis, parthenogenically and fills the gall with 50–70 female offspring. The second generation develops wings and disperses, repeating the process. The third generation includes both males and females. Towards the end of summer, the thi ...
