Sergiusz Toll

Sergiusz Graf von Toll (22 November 1893 – 19 December 1961) was a Polish entomologist who specialised in microlepidoptera and particularly Coleophoridae.

In 1930 he started work as an apprentice at the National Scientific Institute in Bydgoszcz, and between then and 1934 he studied the lepidoptera of the region, joining the Polish Entomological Society and founding its North Silesian branch.

[5] His interest in Lepidoptera continued, and after World War II he became the head of the Nature Conservancy Department of the Directorate of State Forests.

He became a member of the editorial board of the Microlepidoptera Palaearctica, and was writing the Coleophoridae section, a volume with 1500 pages and 5000 drawings.

[8] About 100,000 specimens were given to the Natural History Museum of the Institute of Systematics and Evolution of Animals [pl] of the Polish Academy of Sciences.
