Macrosiphoniella tanacetaria
Tansy Aphid
Macrosiphoniella tanacetaria is a small sap-sucking aphid that feeds on tansy (Tanacetum vulgare). Unlike some congeners, it is not attended by ants and produces minimal honeydew. Its gut physiology differs markedly from ant-attended aphids: it lacks significant oligosaccharide synthesis for osmoregulation, instead producing erlose as its primary honeydew sugar.
