Wing venation and Distal-less expression in Heliconius butterfly wing pattern development.

Abstract excerpt

Here we show that major color pattern elements of Heliconius butterfly wings develop independently of wing venation. We recovered a hybrid Heliconius displaying a mutant phenotype with a severe vein deficiency. Although this butterfly lacked most of its wing veins, the large, melanic banding patterns typical of the genus were conserved across the entire wing. The only obvious correlation between vein reduction...
