Eratoneura fulleri
(Hepner, 1967)
Eratoneura fulleri is a leafhopper in the Cicadellidae, Typhlocybinae, described by Hepner in 1967. Research has documented its distinctive brochosome coating—nanoparticles that create superhydrophobic and anti-reflective properties on the . This species has been specifically studied for its brochosome distribution patterns, which include dense clusters on the outer wing edges used for redistribution across the body.

Identification
Eratoneura fulleri can be distinguished from similar leafhoppers by its brochosome characteristics: individuals deposit large clusters of brochosomes on the outer edges of the wings, which are used to distribute particles to other body parts or for 'repairs' when the coating is depleted. This wing-edge clustering is a notable diagnostic feature visible under microscopy.

Distribution
Recorded from Illinois, USA. Distribution records in GBIF are limited to this state.
Behavior
Has been observed depositing dense clusters of brochosomes on the outer edges of its wings. These clusters serve as for redistributing brochosomes across the body surface or for repairing damaged or depleted coatings.
Human Relevance
Serves as a research subject for bioinspired materials development. Its brochosome coating properties contribute to understanding superhydrophobic and anti-reflective surface designs for human-made materials.

More Details
Brochosomes
Eratoneura fulleri produces brochosomes—hollow, soccer ball-shaped nanoparticles averaging ~500 nanometers in diameter, constructed of proteins and lipids. These are formed in the and applied to the body using comb-like spines on the hind legs.
Research significance
This was specifically examined in a 2025 study by Bello and Alleyne on brochosome size variation and wing wettability, where its wing-edge brochosome clusters were documented as a distinctive trait.
