Modeling the diverse geometry of insect wings

Insect wings are a marvel of evolution—they are lightweight, strong, durable, and flexible. These traits are made possible by wing veins, which are strut-like features embedded in the wing surface. These veins form diverse geometric patterns across insects. For many insect species, even the left and right wings from the same individual have veins with unique topological arrangements, and little is known about how these patterns form. In this talk I will present a large-scale quantitative study of these fingerprint-like "secondary veins." I will then present a simple model that can recapitulate vein patterning across many different insect species.  Zoom at  Password: "Locute"    Chris H. Rycroft
