The author Vladimir Nabokov was an unofficial curator of Lepidoptera (butterflies and moths) for Harvard's research collection, and, in his autobiography, he recounts losing a prized gynandromorph as a child when his governess sat on his collection: "… A precious gynandromorph, left side male, right side female, whose abdomen could not be traced and whose wings had come off, was lost forever: one might re-attach the wings, but one could not prove that all four belong to that headless thorax on its bent pin." Shown above is an unrelated gynandromorph blue morpho butterfly featured in "The Rarest of the Rare: Stories Behind the Treasures at the Harvard Museum of Natural History" (Harper-collins Publishers, 2004).
