The river Tisa “blooms” in mid-June. This natural phenomenon is the most attractive to observe from 10^th to 23^rd June until 7.30 p.m., at 150 km of the river course and along a forest walk named Tisa Flower (Tiski cvet) near the gravel works exiting Kanjiža towards Horgos.

It is, in fact, an insect living in this river and it is named Tisa Flower (Tiski cvet). After three years of living in the clay soil, these insects fly out above the water surface and swarm in a love game ritual which ends until the sunset when the insects die.

Tisa Flower species used to be present in other bigger European rivers, but now Tisa is almost the only resort of this species.

On the occasion of this unique natural phenomenon, the Tourist Organization of Kanjiža Municipality and Environmental Association “Tisa Klub” from Kanjiža, organized an international eco-tour convention named “Sustainable Growth and its Importance in Ecotourism” in the hall of the Regional Atelier “Jožef Nađ” on 12^th June.
