Topologies of wing venation networks. A wing can be considered as a network made up of vein junctions (nodes) and the lengths between them (edges). Using segmented wing images, where each 2D component of the wing is mapped out, we characterize a network using a common community detection algorithm, maximum modularity. Here we show a sampling of wing types and their resultant patterning of clusters, or communities. These communities describe node densities where vein junctions of high relatedness are grouped, based on proximity. Colors of communities represent relatedness.
