Domain shapes, sizes and distributions. (A) Circularity and fractional area characterize the distribution of polygonal shapes that make up the vein-bounded domains within wings. (B) Domain distributions of all the domains within a wing for five representative wings. Color distinguishes domains for each of the species represented (i.e. dark gray domains are from Diptera, D. melanogaster). (C) Along the proximal (wing base) to distal (wing tip) (P–D) axis across a wing, we show an average distribution of domain size and area, where fading color (lighter=wing base, darker=wing tip), indicates span of the wing for six insect orders.
