Are a butterfly and a caterpillar the same animal genetically?

How can an organism achieve such a drastic transformation using the same genome? Does a caterpillar's DNA undergo a rewrite when it metamorphoses? Is there some sort of inherent gene editing going on?

They have the same genome yes. And it shouldn't be that surprising, the same genome that produces your eye is the same genome which produces your kidneys, two very different organs. One of the biggest discoveries from the human genome project was that the absolute number of genes is not that high, it's the regulation of expression and splicing which allows for the huge amount of diversity in tissues.
