Toshio Sekimura, H. Frederik Nijhout. The first book to present the recent genetic and molecular insights into butterfly wing pattern development. Offers an integrative approach to understanding the diversity of butterfly wing patterns. Includes the necessary research fields to analyze the diversity: evo-devo, eco-evo, developmental genetics.

Butterfly wing patterns are organized along Ground Plans, which are compartments for different intervein pattern elements (Figure 1). These pattern elements include eyespots, ellipses, and midlines. The Ground plan, at least for nymphalids, has three symmetry bands: the basal system closest to the body, the central system, the border system.
Butterfly Wing Patterns
Butterfly wing patterns are highly diverse and have complex biological functions. • Diversification of wing patterns can occur at the intra- or inter-specific level. • Both genetic and environmental factors can influence wing patterns. • Diversified wing patterns are a reconciliation of evolution and developmental constraints.

Secrets of butterfly wing patterns revealed by gene hacking New Scientist
Butterfly wing patterns provide a prominent model for studying the development and genetic regulation underlying evolutionary changes. This is because slight shifts in gene expression of a few master genes, such as WntA, affect the expression of several other genes, which can be directly observed as wing color and pattern variations ( 2 - 7 ).

Butterfly wing patterns derive from a deeply conserved developmental ground plan yet are diverse and evolve rapidly. It is poorly understood how gene regulatory architectures can accommodate both deep homology and adaptive change. To address this, we characterized the cis-regulatory evolution of the color pattern gene WntA in nymphalid.

Patterns formed by the colors depend on where and when these genes are expressed. Red color in Heliconius butterflies is associated with the expression of a.

Butterfly patterning and coloring comes from a few specific genes; however, it's not just the genes but also a complex network of regulatory sequences and signaling pathways that lead to diverse, species-specific patterns in butterflies. These interactions instruct pigment coloring, patterning and iridescent qualities.

In general, butterflies use the upper surfaces of their wings to seduce the opposite sex, whereas they use the lower surfaces to hide from view or to communicate to their predators that eating them would be toxic. We have identified a gene that is responsible for creating the upper surface "seductive message" patterns.

The typical color pattern elements on the wings of most butterfly species and also many moths can be understood as derivatives of the Nymphalid ground plan (Fig. 2).The Nymphalid ground plan was originally proposed by Schwanwitsch and reintroduced into the recent scientific discourse by Nijhout as a paradigm for understanding the development and determining homologies among the patterns found.
