Oncopsis flavicollis
This record describes Oncopsis flavicollis (species). Recorded family: Cicadellidae. Recorded order: Hemiptera.
Identification and Appearance

Length 4.5 - 5.5; females larger than males. Sexually dimorphic and variable in colouration and intensity of markings. Nymphs cannot be verified. Males have dark scutellum with yellow spots towards apex and dark veins on forewings, with hyaline cells often with smoky suffusion at the apex. Males usually have extensive dark markings on the face with prominent discoidal spots extended into two dark streaks down the face, but this is variable. Examination of male genitalia (pygofer appendages) will separate from O subangulata . There are several female colour forms; a common form has a yellow-green face and foreparts, but they can also be brown all over. The shape of the ovipositor is shorter and more curved than O subangulata. Other Oncopsis , including O. subangulata also associated with Birch; the two species are often found tgether Detailed examination of the specimen is needed to identify this species. Clear photographs of the face should be provided. You must note the host plant. Common. (ref.: UK Auchenorrhyncha checklist 2021, on British Bugs website) Occasionally recorded; probably common in suitable habitat https://www.britishbugs.org.uk/homoptera/Cicadellidae/Oncopsis_flavicollis.html

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