Ummm... peppered moths are not a good example at all... Peppered moths don't rest on tree trunks during the day.
‘But the problem is that we do not know the resting sites of the moth during the day time. In 25 years we have found only two betularia on the tree trunks or walls adjacent to our traps (one on an appropriate background and one not), and none elsewhere.’-British scientist Cyril Clarke.
Then you might talk about all those photos. Do you really want to know how it was done? Dead moths were glued to the tree-D.R. Lees & E.R. Creed, ‘Industrial melanism in Biston betularia: the role of selective predation’, Journal of Animal Ecology 44:67—83, 1975
Also, there are many contradictory evidences of population changes. In some industrial areas, yes, the dark moths dominated, but in many other industrial areas the light moths dominated. In some non-industrial areas, dark moths dominated, in others, light moths.
Ironically, this really isn't evidence for evolution, it is just a shift in population. Take this analogy, cull out everyone but black people in the world. (no offense intended). Is this an increase in information? No!
