In Bosnia & Herzegovina, the Society for Biological Research and Protection of Nature are living up to their organisation’s name. In a project funded by the Critical Ecosystems Partnership Fund (CEPF), the Society have first conducted a lot of biological research on freshwater biodiversity, and then are using that data to propose protected sites that are very important for nature in the country. …

“This project aimed to identify the most important freshwater habitats for the conservation of threatened dragonfly, mollusk and fish species in the Neretva catchment, and to ensure sufficient scientific data for their efficient protection and long-term survival,” said Dejan Kulijer from BIO.LOG (the short name for the Society for Biological Research and Protection of Nature).

The team have proposed four new Natura 2000 sites, and three of the sites would represent the first designated for threatened dragonfly species Coenagrion ornatum and Cordulegaster heros in Mediterranean Europe. …

For such a small country, Bosnia & Herzegovina supports a large number of dragonflies – over 50 species in all. These flying predators are fantastic ambassadors for freshwater habitat conservation: beautiful animals that rely on clean water in all stages of their life cycles. …

Having reliable data on threatened species is also a valuable contribution against impending dam threats too. The project also discovered that Neretva Softmouth Trout – an endemic fish species – has a significantly reduced distribution in the Neretva basin due to dam and reservoir construction. …

Top threats for dragonflies in Europe:

1. Dams and water management

2. Domestic and urban pollution

3. Droughts

4. Agricultural pollution

5. Tourism and recreational development

This video is about the emergence of a young female Cordulegaster heros dragonfly.

Insects in warm Dutch December

Male common darter dragonfly, photo by L. Tettenborn in the Netherlands reports that in unusually warm December 2015, unusually many crickets and grasshoppers were seen: seven species.

Not only two damselfly species were seen, as usually: common winter damselfly and Siberian winter damselfly; but also (unusually late) adult common darter dragonflies.

Dragonflies quarrel, video

This video, by Everdien, was recorded near a pond in Wekeromse Zand nature reserve in the Veluwe region in the Netherlands.

A vagrant darter dragonfly sat quietly on a tree trunk. Until another dragonfly arrived, and they started quarreling.

Good rare dragonfly news

This is a southern darter video from the Czech republic.

Translated from the Dutch Vlinderstichting entomologists:

November 5, 2015

In the past three years, a very rare dragonfly has settled in the Netherlands: southern darter. After an invasion in 2013, it has by now been seen regularly for two years and there is even breeding.

New nature reserve attracts rare birds, dragonflies

This 2012 Dutch video is about nature reserve Beuningse Uiterwaarden, in Gelderland province, not far from Nijmegen city. It shows birds, konik horses and other animals there. Eg, great crested newts live there as well.

There has been reconstruction early this year. That attracted nesting little ringed plovers.

And rare damselfly and dragonfly species: goblet-marked damselfly; lesser emperor dragonfly; red-veined darter; and scarlet dragonfly.

Rare dragonfly in southern Netherlands

This video from the USA says about itself:

Finding Uncommon Dragonfly Species

Mud Lake is a subalpine fen near Skalkaho Pass, Montana. Fens are infrequent, as such the community of species using this habitat are
uncommon to rare. I have visited this site several times looking for two particular dragonfly species found here: Lake Darner (Aeshna
eremita) and Subarctic Darner (Aeshna subarctica) [aka Bog Hawker]. This video captures the adventure and my happiness in finally finding and photographing them on September 9, 2013.

Translated from the Vlinderstichting in the Netherlands:

In 2013 there already was a sighting of a bog hawker in the Kampina nature reserve in North Brabant province and this year they are seen again. That seems like this rare dragonfly is establishing itself there. They are otherwise only found in the northern half of the Netherlands.
