Butterfly wings are characterized by shingle-like scales (above), which keep water from pooling, and microgrooves (below), which repel water and reduce surface adhesion. These features help keep the surface free of debris and contaminants.

Rice leaves are characterized by waxy bumps (above), which repel water and prevent contaminants from adhering to a surface, as well as grooves (below) that keep water from pooling on a surface. Incorporating these features into man-made products could help engineers tackle unwanted biological build-up in a wide variety of industries.
