Alexander claims that to be an entomologist you need to be born one. He began collecting butterflies as a child. This hobby determined his choice of profession. Alexander Zhdanko has discovered more than 130 species of butterflies and is a well-known entomologist in scientific circles.
One glance at a butterfly flying by is enough for him to tell literally everything about it: from its scientific name and habitat to its diet. To accumulate this knowledge, Alexander Borisovich spent many years in academic libraries of St. Petersburg. He also happens to be a graduate of the world's best school of entomologists in St. Petersburg.
