Admire the ephemeral species 'reunion' on the river

In the late spring and early summer every year, millions of long-tailed ephemera floated to the surface of the Tisza River (Hungary) to find partners and mate before they died.

This amazing natural phenomenon makes the Tisza River near Tiszainoka one of Hungary's most attractive tourist destinations on the early summer. Tourists come here to see firsthand the millions of long-tailed ephemera (Palingenia longicauda) racing up the river to find their partners before dying.

The growth cycle of long-tailed phytoplankton begins with the larval stage. They grow in mud within 3 years before maturing into adult phytoplankton. Larvae live in small caves under mud in the riverbed, with about 400 caves / m 2 .

After developing to adulthood, the animals only have about 3 hours to mate and lay eggs before dying. With extremely short periods of time, male ephemeral people rushed to find them a suitable partner.

When a mate is found, the long-tailed fleets mate with each other on the water of a river longer than 135km in Tiszainoka. However, the fleeting 'love affair' is not romantic. A female ephemeral is often chased and mated with 20 males.

The plankton will fly from 1 to 3 km before laying eggs into the river. After that, the egg will sink to the bottom and hatch into larvae after about 45 days. European nymphs will then develop for 3 years before developing into adult phytoplankton.

Ephemeroptera is a relatively ancient insect that has been around for over 300 million years. There are about 2,000 phytoplankton, very wide distribution. Their bodies are small and weak, small heads, large eyes, very weak diaphragm wings are very susceptible to fall, legs are very small, not used for crawling, just let them cling.

Adult fleets do not live a full day, usually only a few hours, because their mouths have degenerated, unable to eat or drink. The adult plankton is short-lived, but the larval plankton live for a long time. Adult mating is mating to lay eggs in the water, larvae must live 1-3 years in the water, then crawl to the shores to become adult fleets.

The larvae often dance after the sun sets into a small butterfly, which is now similar to the adult evanescent, but there is a translucent membrane covering the whole black body, dark wings, not flexible, cannot mate. After the young butterfly molting, there is a transparent, bright and transparent tail, an adult fleeting form. The adult stage does not eat or drink, just worry about mating and laying eggs. Laying off is dead. From the time the eggs hatch into larvae, it usually takes 20-24 times molting, up to 40 times. Phytoplankton larvae are delicious fish food.
