Acyrthosiphon pisum
This record describes Acyrthosiphon pisum (species). Recorded family: Aphididae. Recorded order: Hemiptera.
Identification and Appearance
The body length of Acyrthosiphon pisum apterae ranges from 2.2 to 5.0 mm long. They are pale green or pink with red eyes. Their antennae are 1.0 to 1.6 times as long as the body. The antennal segments, tibiae and siphunculi have dark apices. The siphunculi are tapering and very thin. with a good image and where the host plant is known. Feeds on about 20 genera in the family Fabaceae but especially on Medicago, Melilotus, Trifolium, Dorycnium and Lotus. Because of the lack of records it is very difficult to assess the status of this species in Britain but it is probably quite frequent. https://influentialpoints.com/Gallery/Acyrthosiphon_pisum_Pea_aphid.htm

About True Bugs, Cicadas, Hoppers, Aphids and Allies: the wider group
Order-level background for Hemiptera, the group containing Acyrthosiphon pisum. 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.
