Extinct mayflies back in the Netherlands


This video shows Ephoron virgo, burrowing mayflies, in the Blauwe Kamer nature reserve, near Opheusden in the Netherlands; 5 August 2015.

According to the Dutch entomologists of EIS Kenniscentrum Insecten & andere ongewervelden today, this species had disappeared from Dutch river banks 79 ago because of pollution. In 1936, the last mayfly was seen where once there had been millions of them.

After the river water had become cleaner, in 1991 the first mayfly larva was found again in the Netherlands. Now, they are getting more numerous in some places along Dutch rivers. The adults are seen only in August.

    VOGELS KIJKEN IN DE BLAUWE KAMER.

    We waren per ongeluk vroeg wakker, deze zaterdagochtend en met het
    krieken van de dag waren we al in de Blauwe Kamer. Els kijkt anders
    naar vogels dan ik. Zij ziet vooral sfeer, zeg maar kunst en ik zie
    “gewoon” vogels. Op haar verzoek maakte ik een aantal sfeerfoto’s en
    vermengt met de mooie ochtendnevel zijn het ware kunstwerken geworden.
    Een aalscholver met zijn vleugels gespreid onder een boompje met een
    groene pruik, een zilverreiger in ochtendlicht en ochtendmist, kortom
    genieten dus!
