1884 or 1887. In 1884 the growing company moved to the larger "Villa Sphinx" and ten years later a two-story wing had to be added. From the mid-1880s onward Staudinger entrusted the company business more and more to Bang-Haas and concentrated on his work in Lepidoptera taxonomy. Staudinger died on 13 October 1900 during a recovery trip in Lucerne, Switzerland. Further important collecting trips 1860 Norway, Finnmarken (with M. F. Wocke). 1862 Castilia, La Granja, San Ildefonso. 1866 Southern France, Ardèche. 1872 Cilikian Taurus (with E. Funke). 1875 Turkey, Amasia (with E. Funke and F.

Bang-Haas and son Paul). 1887 Algeria, Biskra and Lambèse, Djebel Aures. Several shorter trips to the Alps. Achievements and impact One of Staudinger's most valuable and durable achievements was the publication of three catalogues of the Lepidoptera of Europe and eventually of the entire palaearctic region. These "Check-lists" as they would be called today were immediately accepted by lepidopterists, used as a basis of faunal lists and stimulated further taxonomic studies. As early as 1861 Staudinger together with Max Ferdinand Wocke published a Catalog der Lepidopteren Europa's und der angrenzenden Länder [Catalogue of the Lepidoptera of Europe and adjacent countries], himself treating the so-called Macrolepidoptera, and Wocke the Microlepidoptera. The next edition, bilingual in German and French, appeared in 1871 (Catalog der Lepidopteren des Europaeischen Faunengebiets [Catalogue of the Lepidoptera of the European Faunal Region]) and found wide distribution. The 1901 edition became a standard work of reference; it was edited after Staudinger's death by Hans Rebel who wrote the Microlepidoptera part while Staudinger had treated the Macrolepidoptera: Catalog der Lepidopteren des palaearctischen Faunengebietes [Catalogue of the Lepidoptera of the Palaearctic Faunal Region]. Staudinger also played a key role as an initiator of entomological and biological exploration in many parts of the globe. He not only bought collections from the eastern Palaearctic and many tropical areas but he often sent collectors and naturalists to specific areas of interest: Amur and Ussuri regions (Vladivostok, Suifun, Sutschan, Isle of Askold: F. Dörries and brothers, 1877–1898, Jablonovoi-Mountains ["Apfelgebirge"], 1896), NE Siberia (Vitim: O. Herz, 1888), Tarbagatai (near Zaysan: J. Haberhauer, 1877), Altai (near Ongadai, Bashkam, Tshuja valley: Henry John Elwes and Borezowsky, 1898), Mongolia (Uliastai: a cossack collecting for H. Leder, 1893; Kentei
