Plant names are only a part of the taxonomic controversy, however. Naming animals after racists, fascists and other controversial figures cause just as many headaches as those posed by plants, say scientists. Examples include a brown, eyeless beetle which has been named after Adolf Hitler. Nor is Anophthalmus hitleri alone. Many other species’ names recall individuals that offend, such as the moth Hypopta mussolinii.

The International Commission on Zoological Nomenclature (ICZN) has so far refused to consider changing its rules to allow the removal of racist or fascist references. Renaming would be disruptive, while replacement names could one day be seen as offensive “as attitudes change in the future”, it announced in the Zoological Journal of the Linnean Society last year.
