Erythroneurini

Erythroneurini is a tribe within the family Cicadellidae, commonly known as leafhoppers. This tribe belongs to the subfamily Typhlocybinae and is characterized by small, often brightly colored insects that are typically intricately patterned. Erythroneurini species are distributed worldwide, with a higher diversity in tropical and subtropical regions.

Members of Erythroneurini are phytophagous, feeding primarily on plant sap through specialized mouthparts. They often have a significant impact on their host plants, with some species considered agricultural pests due to their ability to transmit plant pathogens, such as phytoplasmas and viruses. Their feeding behavior can cause leaf mottling, curling, and overall plant stress.

Taxonomically, Erythroneurini is distinguished from other tribes in Typhlocybinae by specific morphological features, including wing venation patterns, the structure of the male genitalia, and coloration. Adult leafhoppers in this tribe are typically small, measuring a few millimeters in length, and exhibit a range of coloration from green and yellow to red and orange, often with distinctive markings.

Research into Erythroneurini has contributed to understanding insect-plant interactions and the evolution of leafhopper diversity. Their ecological role includes serving as prey for various predators and parasitoids, thus integrating them into broader food webs.

Overall, Erythroneurini represents a diverse and ecologically important group within the leafhopper family, with ongoing studies aimed at clarifying their taxonomy, behavior, and impacts on agriculture and ecosystems.
