6/20/2023 0 Comments The Virgin and the Bull by Erato![]() Here, we reveal that divergent color patterns contribute to mate recognition between the incipient species Heliconius himera and H. Heliconius butterflies are well known for their diversity of bright warning color patterns, and their amenability to experimental manipulation has provided an excellent opportunity to test their role in reproductive isolation. Addressing this requires experiments to determine the exact cues involved as well as estimates of assortative mating in the wild. However, their importance during speciation will depend on the extent to which they contribute to reproductive isolation. Evidence for these so-called "magic traits" now exists across a range of taxa. Theoretical models suggest that traits under divergent ecological selection, which also contribute to assortative mating, will facilitate speciation with gene flow.
