Article Summary
Butterfly wings cannot be very far behind geckos' toes so far as sources of inspiration for biomimicry research goes. Various properties of the wings of lepidopterans have triggered research into banknote forgery prevention, light reflection and solar cells. New research from Ohio State University suggests the delicate membranes may hold clues to dirt-resistance surfaces.
