Escher and (Homer's?) Chapman ( in "Father's Butterflies", from "Nabokov's Butterflies",  Allen Lane, The Penguin Press,2000):
 
208: .".. and, secondly, made an attempt ( as did Chapman and...) to define the initial stages of the now 'isolated' species in order to compare them to the same stages of the species that formerly 'contained' it"..." And in fact my father's discovery of the Terzit caterpillar made it possible to adopt an entirely new, quite unexpected approach in juxtaposing "Terzit" with "Icarus" [ the Common Blue] and Escher's Blue.
 
Would "Escher's Blue" be applicable to a special butterfly or did VN make a reference to the Dutch engraver Escher? Is there a famous entomologist named Chapman? ( There is another real "Escher")
