Rosy Leaf-curling Aphid agg.
Dysaphis devecta agg.
This record describes Dysaphis devecta agg. (species). Recorded family: Aphididae. Recorded order: Hemiptera.
Identification and Appearance
The Dysaphis devecta species group includes three species of aphid: D. devecta , D. anthrisci and D. chaerophylli . All members of the D. devecta group roll the edges of apple leaves and turn them red to produce a characteristic gall. Please provide good quality images and state the host species when recording. Galls may occur wherever the host species are found. Galls may be found when the host species are in leaf. Dysaphis devecta does not host alternate but remains on Apple throughout the year. D. anthrisci host alternates between Apple and Cow Parsley and D . chaerophylli host alternates between Apple and the leaf bases of various Chaerophyllum species. Status in Britain is difficult to determine due to lack of records. https://influentialpoints.com/Gallery/Dysaphis_devecta_species_group_rosy_leaf-curling_apple_aphids.htm

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