My thesis explores the evolution of elaborate female ornamentation across several temperate dance fly species (Diptera: Empididae).
While evidence of sexual selection on females is relatively common, sex-specific female ornamentation is rare. This is presumably because diverting resources from fecundity to ornamentation could be selectively disadvantageous for both a female and her male suitors; both sexes would suffer if total fitness was depressed by maladaptive over-investment in ornaments. Using dance flies as a model, I am exploring several hypotheses to investigate how and why female ornaments might evolve.
