From D. E. Zimmer's notes: Agrotis pilgrami, Rebel: a moth dedicated to Pilgram, the "Aurelian" (chrysalid lover) of the story. It is an invented species of the noctuid family. However, neither the genus nor Rebel are inventions. The genus is Agrotis Ochsenheimer, 1816 (ex Scotia), some species of which are nasty agricultural pests, and it is to be feared that Pilgram's insect will turn out to be one too. Dr. Hans Rebel of Vienna (1861–1940) who allegedly named this insect in honor of Pilgram was one of the prominent turn-of-the-century lepidopterists, the editor of "Berge's Schmetterlingsbuch" and co-author of Staudinger's commercial catalogue of Palearctic Lepidoptera. So Pilgram was honored by quite an authority of his time.
