The paper Selective bird predation on the peppered moth: the last experiment of Michael Majerus is one of the most downloaded and cited articles in Biology Letters in 2012. As Bruce Grant, one of the coauthors, said to me privately, “It is encouraging that the Biston evidence, presented by those of us who actually know it, is being widely read.” Biston is the genus of the peppered moth, B. betularia.
