The evolution of wing pattern is unclear among automolis, and varies within the genus viviennea watson some species have spotted wings and some species have transversely banded wings, with the bands being parallel or orthogonal (fig 2) the first hypothesis is that the transversely banded wing pattern arose once and is shared by. The evolution of wing pattern diversity in butterflies has emerged as a model system for understanding the origins and maintenance of adaptive phenotypic novelty admiral butterflies (genus limenitis) are an attractive system for studying wing pattern diversity because mimicry is common among the north american species and. The heliconius butterflies are one of the classic systems in evolutionary biology and have contributed hugely to our understanding of evolution over the last 150 years.
