Early life and career
Obraztsov was born on 18 August 1906 in Rostov on the Don, Russia, to Dr. Sergei Nikolaevich Obraztsov and his wife, Ludmila Nikolaevna Obraztsova.

Research
The subjects of his research were revisions of the family Ctenuchidae of the world and of the family Tortricidae, first of the Palaearctic, later of the Nearctic and Neotropical regions. By systematically indexing the lepidopterological literature Obraztsov created a catalog with more than 30,000 entries and became the recognized leading specialist in his field. The most significant results of his taxonomy were published in the journal Tijdschrift voor Entomologie in 1955. In addition, Obraztsov published more than 130 other scientific works from 1926 to 1966.

Numerous species of Tortricidae were first systematically categorized by Obraztsov, including Argyrotaenia urbana, Cochylidia contumescens, Choristoneura lambertiana, and Cochylidia oblonga.
