The insect collection of the Senckenberg German Entomological Institute (SDEI) in Müncheberg is one of the largest and most important natural science collections of its kind in Germany. It is an essential part of the complementary international network of biodiversity research.
It currently comprises approximately 3 million specimens in 190,000 species, including types from 22,000 species. The 13,000 boxes of the uniformly structured, well-organized collection are housed in an air-conditioned storage facility in an electronically controlled compact shelving system. The foundation of the collection is made up of special collections from outstanding entomologists, which were mainly acquired by the SDEI as bequests. These include, for example, the KRAATZ (Coleoptera), HORN (Coleoptera: Cicindelinae), LEONHARD (Coleoptera and Lepidoptera), and VON HEYDEN (Palaearctic Coleoptera) collections. Particularly valuable are the collections of SAUTER (1871-1948) from Formosa (approx. 6,000 species, numerous types) and from the DEI expedition to Albania in 1961.
In principle, insects of all orders and from all zoogeographical regions are collected, but the focus is on the orders Coleoptera, Diptera, Lepidoptera, and Hymenoptera, which are traditionally processed by SDEI staff. In addition, material on the biology of all insect groups (larvae, pupae, mines, feeding patterns, structures, etc.) is collected and preserved.
With a few exceptions, the collection items, including hemimetabolous insects, are classified in the main collection using standard box sizes according to principles formulated by Walther Horn and documented in catalogs or in the SDEI database.
The SDEI’s type collections have been largely published and are already partially accessible via the Internet. The wealth of types requires the provision of material in an intensive international exchange.
Database-supported digitization of type material from Taiwan
(Third-party funding: National Museum of Natural Science (NMNS) in Taichung, Taiwan)
The SDEI insect collection is renowned for its extensive “Formosa Collection,” consisting of approximately 6,000 species, including numerous types and 2,258 species from Taiwan. These insects were collected by Hans Sauter between 1908 and 1914 (LINK: 1009683 ESAKI 1941.pdf) in Taiwan and donated to the institute. The SDEI gave the Taiwanese specimens to the respective specialists for processing and ensured that the results were published. Because of this history, Taiwan was for a long time the most entomologically researched island in Southeast Asia.
The National Museum of Natural Science (NMNS) in Taichung, Taiwan, signed a cooperation agreement with Senckenberg in 2007. This made it possible to digitize the type material of the Formosa Collection in stages. The results are accessible via the NMNS online database. Entomologists from all over the world can now search online for photographs of the type material for their research without having to borrow them.
