Long-tailed mayflies (Palingenia longicauda) fly over the surface of the Tisza river near Tiszainoka, 84 miles southeast of Budapest on Wednesday. Millions of these short-lived mayflies engage in a frantic rush to mate and reproduce before they perish in just a few hours during "Tiszaviragzas" or Tisza blooming season from late spring to early summer every year.
