feronia butterflies experimentally with regard to their choice of resting sites, to investigate how that relates to their biology and behavior, and perhaps to be able to provide a new example of the industrial melanism concept.
Another aspect of these results is their relevance to the concept of industrial melanism.
feronia is a well known species that has fixed both, genetically and morphological together, and therefore evidence of behavior increasing fitness related to wing coloration support the industrial melanism theory without the methodological problems that B.
Majerus asserted that we must dismiss industrial melanism
in Biston Betularia (peppered moths) as an exemplar of natural selection but that the basic tenets of ecological genetics and evolution forwarded by Kettlewell and ford still stood firm.
