I do find the lulworth skipper thing interesting, I just kind of wonder what someone seeing a Camberwell beauty or Kentish plover in Europe thinks when they learn their English names.Actually you've justified both eponyms and place-names here for me too: they do tell you something about the history of natural history, one of the things being the sources of and investment in enquiring science and another, which individuals made contributions to science. Why should Chemistry and Physics have Hooke's Law, Avogadro's number etc but biology be devoid of recognising individual work?
I find it interesting and an assistance to memory to know that Pallas's Warbler, Pallas's Grasshopper Warbler (I wonder what Peter Pallas would think of "Gropper"?) Pallas's Fish Eagle are associated - not necessarily with finding always, but that's part of the interest in reading up - with one expeditionary naturalist. Ditto Steller with Sea Eagle, Jay and the sadly extinct Sea Cow (oh look, a cautionary tale for the reader.) It's interesting that Lulworth Skipper was described in Dorset prior to the rest of its range. Worth reading generally into the development of interest in scientific investigation and classification?

I guess the reality is that they have established names in other languages too presumably with their own idiosyncrasies even if there are also places like here where people from round the globe discuss them in English.
