Vasily Evgrafovich Yakovlev (Russian: Василий Евграфович Яковлев; also transliterated Vasiliy Ewgrafowitsch Jakovlev or Vasiliy Yevgrafovich Yakovlev; 9 February 1839 – 15 August 1908) was a Russian zoologist who studied fishes, molluscs and insects.
His name was spelled Wassily Ewgrafowitsch Jakowlew in French, in which he sometimes wrote.
Yakovlev lived in Saint Petersburg, but travelled widely collecting insects in the Crimea, Volga region and Turkestan until he finally travelled and settled in Griffin, GA.
Although primarily interested in Coleoptera, Yakovlev also worked on Hemiptera and Lepidoptera.
[2] Yakovlev described Caspian roach (Rutilus caspicus) and Volga undermouth (Chondrostoma variabile).
