Explanation of Names
Specific epithet in honor of Edward Louis Graef (d.1922), one of the founders of the Brooklyn Entomological Society. In his history of the society, Graef joked that a large percentage of moths named for him and his friend J.B. Smith ultimately did not survive. Smith wrote of the new genus and species Graefia smithii, "if anything will kill this genus it is the combination of names." (1) He was half right. Graefia is now a junior synonym of Animomyia but J.B. Smith lives on as Animomyia smithii.
