Eratoneura affinis
This record describes Eratoneura affinis (species). Recorded family: Cicadellidae. Recorded order: Hemiptera.
Identification and Appearance
Similar to E. basilaris . Basal shading averages lighter and more orangey. There is a large, squarish white patch in the center of the brown area, near the scutellum. The distal margin of the brown zone is also interrupted at the costal margin by a white patch ( 3 ) . Both species also have a color morph without the dark basal shading. These cannot be distinguished from various other genus members without male dissection ( 3 ) . Det. Solomon V. Hendrix, 2020

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