Bug BioEngineering: a defense against other "bugs"

Recently it has been discovered that cicadas wings aren't bacteria free due too chemicals, but instead use a clever piece of engineering to prevent the pesky pests from living on their wings.  The cicadas have nano-pillars on their wings that are the same size as the bacteria and as the bacteria settle the nano-pillars stretch the bacteria causing it to rupture.
