Oncopsis subangulata
This record describes Oncopsis subangulata (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 weak dark markings on the face and lack the prominent discoidal spots of O flavicollis, but this is variable. Examination of male genitalia (pygofer appendages) will separate from O flavicollis . Females have a heart-shaped rusty-brown area on the face, with a darker border. The shape of the ovipositor is longer and straighter than O flavicollis. Other Oncopsis, especially Oncopsis flavicollis . Both species are associated with birch and are often found together Detailed examination of the specimen is needed to identify this species. Clear photographs of the face should be provided. Provide measurement and whether male or female. You must note the host plant. Local.

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