In a new article in PLoS ONE, a group of researchers led by Kevin Edwards present a collection of images of Hawaiian Drosophila wings. Here's one figure from the paper showing the evolutionary relationships of a bunch of different clades and some representative wing patterns:
The authors point out that, with the availability of the Drosophila grimshawi genome sequence, biologists can now use molecular techniques to understand the genetic changes that give rise to the various pigmentation patterns.

Ah yes, the wonders of regulatory evolution.
Carroll and company just recently published a paper covering the general principles surrounding regulatory evolution:
