Ceratagallia calcaris
Ceratagallia calcaris is a leafhopper species in the family Cicadellidae, known primarily as a vector of the yellow vein disease agent affecting sugarbeets. It acquires the pathogen through phloem feeding on infected plants, undergoes a latent period of 9–18 days, then transmits the agent for life. The species breeds on sugarbeets and overwinters on kochia (Kochia scoparia). It is distinguished from other leafhopper vectors by its specific association with this disease agent.
