Dietrich von Schlechtendal

Dietrich Herrman Reinhard von Schlechtendal (20 October 1834 – 5 July 1916) was a German entomologist who worked on Cynipidae.

Working on the North American species Neuroterus quercus-batatus (Fitch) in a laboratory, he bred from the parthenogenetic females the bi-sexual form.

This species was then introduced onto Turkey oaks in the Halle Botanic Garden.

His collection of Cynipidae with their galls is shared by the Museum für Naturkunde in Berlin and the Zoological Institute of the University of Halle-Wittenberg which also conserves his collections of Blattidae and Lepidoptera.

As well as many short scientific papers, Schlechtendal wrote Die Gallbildungen (Zoocecidien) der Deutschen Gefässpflanzen (1891).
