Sorry, respectfully, you're just repeating what someone told you in a book or that you saw on television. They adapted. Plenty of animals adapt to the change of season, by having a white coat. The moths adapted by changing color based upon environemnetal changes. They did not become super-moths.
And why should they? They adapted enough to preserve their genome, which is what survival is all about. The stresses placed on them were enough to induce that much change, but greater change was not necessary. Nature is economical and doesn't produce what isn't needed. If we introduced birds capable of supersonic flight, the moths would become super moths or become extinct.
