A long-tailed mayfly rests on the face of a man at the Tisza river near Tiszakurt
A long-tailed mayfly (Palingenia longicauda) rests on the face of a Hungarian man, Balazs, at the Tisza river near Tiszakurt, 135km (84 miles) southeast of Budapest, June 12, 2011. 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.
