Cavariella theobaldi
This record describes Cavariella theobaldi (species). Recorded family: Aphididae. Recorded order: Hemiptera.
Identification and Appearance
The body length of Cavariella theobaldi apterae is 1.8 to 2.8 mm. For further details please follow the ‘Further info:’ link below Unless identified by a recognised expert, a photo is required. If the photo doesn't show the key ID features, then in the comments box describe the size and identifying characters you have observed. Please provide a note of the food plant. Wherever the host species* occur (*see under ‘Life History:’ below) Aphids may be found whenever the host species are in leaf. Cavariella theobaldi host alternates between Willows ( Salix species) and some umbellifers mainly Wild Parsnip ( Pastinaca ) and Hogweed ( Heracleum ). The species appears to be widespread in Britain, but true status is difficult to determine due to lack of records. https://influentialpoints.com/Gallery/Cavariella_theobaldi_Willow-parsnip_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 theobaldi. 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.
