I wasn’t going to write about Carl Zimmer’s NY Times piece “Nabokov Theory on Butterfly Evolution Is Vindicated,” since it has to do with neither language nor hats, but people keep sending me the link, so I bow to popular demand. As everyone who cares about Nabokov knows, he was mad about butterflies, and enough of an expert on them to have had articles published. (In fact, there’s a whole book on the subject.) He had a theory, which professional lepidopterists didn’t take seriously, that the Polyommatus blues (example) came to the New World from Asia in a series of five waves, spanning millions of years. Now they discover that, lo and behold, he was right: “‘By God, he got every one right,’ Dr. Pierce said. ‘I couldn’t get over it — I was blown away.’” This would, I am sure, have pleased the old fellow considerably more than the fuss over the publication of the scraps of his last novel.
