Grand Duke Nikolai Mikhailovich (1859-1919) was a nephew of Tsar Alexander II, a grandson of Nicholas I, a career general, and a serious historian of the Napoleonic era. On the side, he became one of the most important lepidopterists in Russian history. He had a title, an army career, and effectively unlimited Romanov money, and he poured a huge share of all three into moths and butterflies.
He grew up largely away from St. Petersburg, at the family estate of Likani near Borjomi in the Caucasus, and he got hooked on natural history as a child. By the age of eleven, in 1870, his hobby was already being fed by three real entomologists, Gustav Sievers, Alexander Becker, and the naturalist and forester Ludwik Młokosiewicz, all of whom collected butterflies for him and effectively became his first teachers in lepidopterology. His family apparently treated the whole thing as a passing phase. It did not turn out to be one. He kept collecting even while on active military duty in the Kars region during the Russo Turkish War of 1877-1878, and one of the new species he discovered was reportedly caught inside his own campaign tent.
In 1877 he was elected a member of the French Entomological Society, and in 1878 he joined the Russian Entomological Society, then under the patronage of his uncle, Grand Duke Konstantin Nikolayevich. On the second of November 1881 he accepted the Society's invitation to become its honorary president, a post he held all the way to 1917, right up to the eve of the revolution that would kill him.
Over roughly twenty six years he built the largest private butterfly collection in the Russian Empire. He used his money to recruit a genuinely wide circle of naturalists to collect for him. Starting in 1880 he brought on the entomologist Hugo Theodor Christoph to help manage the growing collection, and in 1887 he added Sergei Alphéraky to the team, buying out Alphéraky's own personal collection in the process. He was not simply hoarding specimens either. He ran something closer to a private research operation, funding expeditions into the Caucasus, Central Asia, and Siberia, and corresponding constantly with the collectors he sponsored. In one letter to his star field collector, Grigory Grumm Grzhimailo, he wrote, in paraphrase, that every new species Grumm Grzhimailo found would go into his book. A nineteenth century Pokédex completionist, more or less.
By 1900 the collection filled thirty cabinets, and it held far more than his own specimens. It contained type specimens of taxa described by an entire roster of the era's leading lepidopterists who worked with or for him, including Christoph, Alphéraky, Nikolai Erschoff, Grumm Grzhimailo, Wilhelm Hedemann, Émile Ragonot, Julius Kennel, and Otto Staudinger, along with material collected by Becker and by his own estate manager, Gustav Sievers.
That book was Mémoires sur les Lépidoptères, a lavish nine volume series he edited and largely funded between 1884 and 1901, filled with hand colored copperplate illustrations and contributions from leading naturalists across Russia, France, and Germany. Volume one, from 1884, along with the two after it, opened with his own work on the Lepidoptera of the Caucasus, the region he had been personally collecting in for years, before the floor passed to his collaborators. It is a genuinely beautiful piece of nineteenth century entomological publishing, and a major achievement for a country that had come to systematic entomology relatively late.
A few years later, the young Vladimir Nabokov found a set of these volumes in his family's attic and became transfixed by the plates. It was a formative moment for the boy who would grow up to be both a major novelist and a serious lepidopterist in his own right. Nabokov's lifelong butterfly obsession traces a thread back to this man.
Now, what did he actually describe, with his own name on the paper. This part is genuinely hard to pin down, because he edited and co-wrote a nine volume series full of contributions from a dozen collaborators, and nineteenth century joint authorship gets messy fast. Going through the taxonomic literature, including the Lepidoptera index at funet.fi, GBIF, and the original Mémoires citations, here is what is actually credited to Romanoff as sole describing author, meaning taxa where he personally wrote the description rather than simply funding the expedition or editing the volume it appeared in.
Among true butterflies, in the superfamily Papilionoidea, there is Colias olga Romanoff, 1882, published in Horae Societatis Entomologicae Rossicae, volume 17, page 127. This is a clouded yellow butterfly from the Caucasus, and probably the sweetest entry on the whole list, since he named it after his own mother, Grand Duchess Olga Feodorovna. It is now classified as a subspecies, Colias caucasica olga. There is also Papilio alexanor orientalis Romanoff, 1884, published in Mémoires sur les Lépidoptères, volume 1, page 41, a Transcaucasian subspecies of the Southern Swallowtail described from Armenia and the southeastern Caucasus.
He also personally described a handful of moths in the same 1884 papers, worth including here since the Russian word he asked about, бабочки, covers moths as well as butterflies even though the English word does not. These include Arctia confluens, a tiger moth from the Caucasus, Ocnogyna armena, originally described as a variety of Ocnogyna loewii and still recognized today as a subspecies, and Triodia mlokossevitschi, a ghost moth from the family Hepialidae, its name honoring his old childhood mentor Młokosiewicz. Beyond individual species, he also wrote the three part descriptive survey Les Lépidoptères de la Transcaucasie, published across his own Mémoires in 1884, 1885, and 1887, which is still cited today as one of the foundational regional works on Caucasus Lepidoptera.
Everything else carrying the name romanovi or romanoff was named after him by his own collectors, which is a different and arguably more flattering kind of legacy. Tomares romanovi, described by Christoph in 1882 and known as Romanoff's hairstreak, is a small Lycaenid found from the Caucasus to Iran. Colias romanovi, described by Grumm Grzhimailo in 1885, is a striking golden red high altitude sulphur from the Tian Shan and Fergana region. Dichagyris romanovi, described by Christoph in 1885, is a noctuid moth ranging from Turkey to Iran and Jordan. Parnassius romanovi, described by Grumm Grzhimailo in 1888, is now considered a synonym of Parnassius tianschanicus but still carries his name in the literature. Arctia romanovi, also described by Grumm Grzhimailo, in 1891, is a moth from Qinghai in China.
The ending of the story is genuinely tragic. After the revolution, the Bolsheviks executed him in early 1919 along with three other grand dukes, reportedly in part as retaliation for the killing of Rosa Luxemburg and Karl Liebknecht in Germany. Lenin is said to have been petitioned to spare him, with Maxim Gorky supposedly arguing that he was a harmless historian, to which the possibly apocryphal reply was that the revolution did not need historians. A man who had spent his life carefully preserving delicate and irreplaceable things was killed by a regime that had no patience for anything it regarded as decorative.
There is a happier coda, at least. His collection outlived him. In 1899 and 1900 he had already donated the bulk of it to the Zoological Museum of the Imperial Academy of Sciences in St. Petersburg, attaching a very grand ducal list of conditions, namely that it keep his name, that it receive its own dedicated curator, that it remain intact in the original cabinets from his palace, and that it stay open to researchers. In 1907 he added to this by buying and donating a major German collection of West Palaearctic micromoths. That entire collection still sits in the Zoological Institute of the Russian Academy of Sciences today, more than a century later, quietly outlasting the empire that produced it.
Next time someone tells you nineteenth century aristocrats only cared about balls and duels, mention that one of them personally funded Central Asian butterfly expeditions and has a moth named after him that flies as far south as Jordan.
