"Earlier this year, we reported about a finding which revealed that physical structure of Psaltoda claripenniscicada wings can shred certain types of rod-shaped bacteria. After analyzing the surface, researchers at the Swinburne University of Technology used biomimicry to create a surface with similar properties. This nanosurface could lead to development of a new generation of nanostructured antibacterial materials. 

“Based on this discovery, we investigated other insects that may possess similar surface architectures that might kill more bacteria, in particular the deadly strains of the Staphylococcus aureus or golden staph bacterium”, said Elena Ivanova, microbiology professor at the Swinburne University of Technology. Their search led them to the wings of the Diplacodes bipunctata (Wandering Percher dragonfly), whose spike-like nanostructure destroys both rod-shaped and spherical bacteria."
