Anew developmental model recreates the vein patterns of insect wings, reported in PNAS on September 17. While previous studies have focused on analyzing primary veins that are largely shared across a species, the formation of secondary veins that are unique to an individual insect is a mystery. By scrutinizing images of 468 different wing patterns from 232 species belonging to the order Odonata (dragonflies and damselflies), the researchers proposed a model to predict secondary vein development. Their algorithm successfully reiterated secondary vein patterning for remotely related winged insects.
