Yarrow Aphid
Røllikebladlus
Duizendbladgalluis
mszyca kwietnokrwawnikowa

It does not host alternate, but does have a sexual stage in its life cycle. Macrosiphoniella millefolii is common and widespread in Europe into Asia and has been introduced into North America.

Macrosiphoniella millefolii mainly feeds on Yarrow (Achillea millefolium), but it has been found on many other Achillea species, as well as on daisies (Leucanthemum), tansies (Tanacetum) and mayweeds (Tripleurospermum spp.) it is usually found in areas where these host plants are present. It causes galls in flower heads; the head becomes rounded or compressed, with thickened petioles.

Overwintering eggs, laid on the stems of yarrow the previous autumn, hatch in spring to give fundatrices. These reproduce parthenogenetically giving birth to live young which mature and reproduce in turn. By mid-June there can be dense colonies of Macrosiphoniella millefolii living on the flower stems of their host plant.
