Motschulsky was an Imperial Army colonel who undertook extended trips abroad.
He studied and described many new beetles from Siberia, Alaska, the United States, Europe, and Asia.
Many of these works are based on studies of insect collections that were created by a large number of other naturalists, especially Russians who had been to Siberia.
He also made collections of other arthropod groups such as myriapods, sometimes describing species under the name of "Victor".
