Willow-carrot Aphid
Cavariella aegopodii
This record describes Cavariella aegopodii (species). Recorded family: Aphididae. Recorded order: Hemiptera.
Identification and Appearance
The body length of Cavariella aegopodii apterae is 1.5 to 2.8 mm, they are greenish or reddish. The alate of Cavariella aegopodii has a central black patch on the abdominal dorsum, and a dark cauda and siphunculi. 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. Please state the host plant when adding your record.Wherever the host plants occur. The Willow-carrot aphid host alternates from Willows (Salix sp.) to umbellifers (Apiaceae). The preferred primary hosts are Hybrid Crack-willow (Salix fragilis) and White Willow (Salix alba). Preferred secondary hosts are cultivated umbellifers such as Carrots (Daucus carota) and Fennel (Foeniculum vulgare) as well as several wild umbellifers. Status in Britain is difficult to determine due to lack of records, but this species is believed to be widespread and fairly frequent. https://influentialpoints.com/Gallery/Cavariella_aegopodii_Willow-carrot_aphid.htm No additional images available for this species.

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