|Peppered Moth, Biston betularia. Norbury Park, 17 June 2012.|
It's an iconic species, often used as an example of natural selection. As well as this form there is a dark-winged form that became common in sooty cities, while this speckled form almost disappeared, though it stayed common in the countryside. Birds were able to pick it out easily against the dark city backgrounds. Since the Clean Air Act in 1956, the speckled form has become more common again.
