The location where I photographed the Cordulegaster boltonii is also a habitat of the in Denmark relatively rare Orthetrum coerulescens.

There were quite a few of them, especially males each aggressively defending their own little territory. Nothing were holding them back from chasing off the much larger Cordulegaster boltonii.

I also saw a few females, most of them forming mating wheels with males.

New photos have been added to the gallery

It has been several years since I last photographed the large and beautifully colored Cordulegaster boltonii. So, this weekend I decided to take a trip to one of its few habitats here in Denmark. At this location there is  a small stream with clear spring water which is the favored type of habitat of its larvae.

The weather was sunny and warm but quite windy. The stream itself was completely sheltered from the wind by the surrounding vegetation and four to five Cordulegaster boltonii were constantly patrolling the stream and resting in the vegetation. So, perfect conditions for getting some good photos which have now been added to the gallery.


The layout and general look and feel of has been updated to be more modern and suitable for mobile devices. The original website layout was getting pretty old so many things have happened since then.

The update is not fully complete yet so things might still change and not always work perfectly.
