The 12th Forum of Russian Entomology is being held in St. Petersburg. Scientists who have devoted their lives to the study of insects are meeting to discuss their problems and exchange the results of their research. Valentin Zaika, who lectures at the Tuvan State University, and his former student, Alexandr Saaya, are now colleagues and are presenting "Tipuloid insects of Tuva" at the forum. Their report arouses special interest because Tuvas unique geographic position has proven to be a center for the formation of many species of insects.
