Nov. 27 (UPI) -- Entomologists in Russia have discovered a new butterfly species with an unusual number of chromosomes. The newly named South Russian blue has 46 chromosomes, the same number as humans.
When Vladimir Lukhtanov, entomologist and evolutionary biologist at the Zoological Institute in St. Petersburg, first captured and analyzed specimens of the South Russian blue butterfly in 1997, he thought they were Azerbaijani blues.
