Cicadas contain some of the smallest & complex Endosymbionts, which seem ro build antibacterial scaffolding cells, or even act as infecting Phage against larger bacteria.

Replica molds of cicada wings give flight to possibilities of antibacterial surfaces
The spiky surface of cicada wings inspires researchers to create plastic or polymer surfaces that can kill antibiotic-resistant bacteria.

Decoding the chemistry behind cicada’s bacteria-killing wings
Meticulously organised fatty acids are responsible for the bacteria-killing, superhydrophobic nanostructures on cicada wings.
