Macrosiphoniella millefolii
This record describes Macrosiphoniella millefolii (species). Recorded family: Aphididae. Recorded order: Hemiptera.
Identification and Appearance

The Apterae of Macrosiphoniella millefolii are of moderate size, green and wax powdered except for a spinal stripe on the abdomen and presiphuncular spots Good photographs required, please state the host species when submitting records. 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 ( Achillea millefolium ) the previous autumn, hatch in spring to give f undatrices . 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. It does not host alternate, but does have a sexual stage in its life cycle. Not regularly recorded in Britain which makes status difficult to determine. https://influentialpoints.com/Gallery/Macrosiphoniella_millefolii_yarrow_aphid.htm

About True Bugs, Cicadas, Hoppers, Aphids and Allies: the wider group
Order-level background for Hemiptera, the group containing Macrosiphoniella millefolii. Species-specific details appear above.
Group overview
Hemiptera (true bugs) includes over 80,000 described species across cicadas, aphids, leafhoppers, shield bugs, and bed bugs. Aphids alone cost global agriculture an estimated $2.5 billion annually in crop losses.
Ecological role of the group
Many Hemiptera are essential food sources for birds and predatory insects. Cicadas provide massive nutrient pulses during emergence events - a single Brood X emergence can involve trillions of individuals across 15 states.
Economic and practical significance of the group
The brown marmorated stink bug (Halyomorpha halys) caused $37 million in apple crop losses in a single year in the U.S. Mid-Atlantic region. Bed bug infestations in the U.S. increased by 500% between 2001-2010, costing the hotel industry hundreds of millions annually.
