Evolution in action.

Now I'm not sure what your trying to say....are you being sarcastic or saying the moths were glued to the trees?

The moths where glued in place for the picture.   Which wouldn't be a problem, however it is misleading in the explanation, as the moths do not normally rest on the tree trunks, but on the underside of leaves (as your article states).

Peppered moths do not rest exclusively on tree trunks, but they do rest there. Of the forty-seven moths one researcher found in the wild, twelve were on trunks and twenty were on trunk/branch joints. (The other fifteen were on branches). The numbers and proportion on trunks near light traps were even higher (Majerus 1998, 123). Wells's claim that the moths do not naturally land on trunks is simply a falsehood
