Insect wing venation patterns, wing contour and shapes of vein-bounded domains. Adapted from Misof et al. (2014), this order-level representation of insect wing venation patterns, shapes and vein domains (as defined in the figure on the right) exhibits the range and diversity of our sampling. Insect orders labeled in light gray are not sampled or characterized as wingless (full species list in Fig. 5A). Wing scale is removed to compare venation, however wing length ranges an order of magnitude. For example, the Odonate wing (green) is 52 mm in length, compared to the 3 mm in length Dipteran wing (yellow). Six orders (bulleted in color) are highlighted throughout this analysis.
