Olympus MIC-D: Butterfly Wing Scale Gallery - Mocker Swallowtail |
 | | There are some cases of gynandromorphic mocker swallowtail butterflies, which are sexual mosaics that display both male and female wing coloration and patterns, and andromorphic females, which display male wing designs. |
 | | By minimizing the ratio of mimetic morphs to model species, mocker swallowtail butterflies may be improving the learning curve for predator avoidance and increasing their fitness. |
 | | As such, the mocker swallowtail butterfly is a favorite laboratory subject of molecular geneticists tracing DNA sequence polymorphisms, island biogeography, and disruptive selection, in which butterflies at either extreme of phenotypes are favored over those with intermediate characteristics in each population. |
