Corylobium avellanae
This record describes Corylobium avellanae (species). Recorded family: Aphididae. Recorded order: Hemiptera.
Identification and Appearance
Corylobium avellanae apterae are usually yellowish-green but in one form the aphid is mottled with red. For additional information see ‘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 also state the host species. Woodland and other areas where Hazel is present. It mainly feeds on the fast-growing shoots and only rarely on the leaves. Corylobium avellanae does not host alternate but spends its entire life cycle on Hazel ( Corylus avellana ). Sexual forms occur in autumn and overwintering eggs are laid on Hazel. True status in Britain is difficult to determine due to lack of records. https://influentialpoints.com/Gallery/Corylobium_avellanae_Large_hazel_aphid.htm

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