Tisza blooming (Tiszavirágzás)
04.07.2008
Solvin Zankl just returned from a one month trip to Hungary’s Tisza River. He documented the Tisza blooming (Tiszavirágzás). It is when millions of long-tailed mayflies (Palingenia longicauda) are rising in huge clouds, reproduce, and perish, all in just a few hours.
