This dragonfly video is called Anax parthenope Anax napolitain ponte Lesser Emperor laying eggs.
From Dutch news agency ANP:
The Maas river valley in the Dutch province of Limburg because of global warming and the founding of new nature reserves increasingly is becoming a fit place for plants and animals which until recently lived only in southern Europe.
Scientists of an ecological advisory agency in Berg en Dal said that this Monday.
For the first time ever in The Netherlands, two scientists in September saw successful procreation by the lesser emperor dragonfly (Anax parthenope) in the Asseltse Plassen near Roermond.
Vagrant specimens of this insect had been seen already a few times since 1998 in Limburg, but procreation along the Maas river had never been proved before.
