Wagner, The Character Concept in Evolutionary Biology, →ISBN, page 513:This figure emphasizes the dislocation of the pigment bands and presents the so-called nymphalid groundplan: the set of pattern elements out of which butterflies build their wing patterns (Nijhout 1991). The groundplan thus consists of eight parallel series of pattern elements: one for each band of each of the three symmetry systems, a row of border ocelli, and a set of submarginal bands. Each wing cell has a representative of each of these pattern elements so the overall groundplan can be viewed as a serial repetition of the same set of pattern elements.
