Condition dependence, quantitative genetics, and the potential signal content of iridescent ultraviolet butterfly coloration.

Abstract excerpt

Structural colors result from an interaction between light and the fine-scale physical structure of a surface, and are often extremely bright, chromatic, and iridescent. Given that these visual features depend upon the aggregate abundance and architectural precision of photonic structures, structurally colored sexual ornaments seem well placed to indicate a range of mate quality characteristics. We tested this...
