Herb Bennet Aphid
Macrosiphum gei
This record describes Macrosiphum gei (species). Recorded family: Aphididae. Recorded order: Hemiptera.
Identification and Appearance
Macrosiphum gei apterae are spindle-shaped, usually mid-green to bluish green or wine red. Unless identified by a recognised expert, a photo is required and the specimen should be examined with a microscope. In the comments box, state the key or ID method used and describe the size and identifying characters. Macrosiphum gei is found in dense colonies on the upper parts of the flower stem of Geum urbanum Herb-Bennet (also known as Wood Avens) and on Hybrid Avens. It can also occur on the undersides of the leaves of some Apiaceae, especially Anthriscus. Status in Britain is difficult to determine due to lack of records. https://influentialpoints.com/Gallery/Macrosiphum_gei_Herb_Bennet_aphid.htm

About True Bugs, Cicadas, Hoppers, Aphids and Allies: the wider group
Order-level background for Hemiptera, the group containing Macrosiphum gei. 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.
Recorded sources for this group: USDA, EPA, University research. Imported estimates may describe particular regions or reporting periods.
