Flowering of the Tisa River (Serbia)-a phenomenon that exists only in Serbia and China

This phenomenon occurs once a year.Tisa Flover, s is a watery insect that once used to be found in other rivers of Europe, but today it is only in Tisa(Vojvodina,Srebia). And the less in Hungary, and much more in Serbia.Except in Serbia on Tisa, there is only one in China on the river Yang Ceng Yang.Insect lives in the sludge at the bottom of the river for three years.After that, they appear above the river and fly in swarms extends their species.This is actually a wedding dance in which the male and female mate, and after the fertilization and laying of eggs, the first male, and then the female, dies.More millions of fertilized eggs begin a new three-year development cycle.It only takes a few hours.
