Empoa rubricola
Empoa rubricola is a species of leafhopper in the family Cicadellidae, subfamily Typhlocybinae. Described by Christian in 1954, this species belongs to a genus of small, often brightly colored leafhoppers. Like other Empoa species, it likely possesses brochosomes—nanoparticles that provide water-repellent and anti-reflective properties to the cuticle. The species has been recorded from northeastern North America including Delaware, New Hampshire, Ontario, Québec, and Wisconsin.
