Dragonfly Wing Architecture — Calopteryx Venation

Description

The wing of the banded demoiselle damselfly (Calopteryx splendens) is a masterpiece of biological structural engineering — a membrane supported by a complex network of hollow veins that collectively form one of nature’s most elegant load-bearing lattices, capable of providing lift and maneuverability at flight speeds up to 35km/h from a structure weighing less than 0.03 grams. This photograph, made with a specially configured bellows and a 65mm macro lens at 4:1 reproduction, resolves individual vein cells of approximately 0.2mm diameter across the full wing surface, the dark blue iridescence of the male’s wing patches creating areas of deep colour within the otherwise transparent venation structure.
