This is not a reprimand... as you take it...! I was simply pointing out a mistake about the ecology of this species. It is indeed a pity to mislead your readers on a wrong information. The fact that I have not participated more than that in this site does not diminish the value of my skills. I also happen to know this lake and your presentation interested me. Other species of dragonflies would be much better than this Calopteryx virgo festiva. I have honoured you with my comment and clarifications. I am not hiding behind any pseudonym and if you had a little odonatological culture, you would know that I am one of the first odonatologists to have written on the sector in the 1980s and that my work and my odonatological skills go far beyond this approach of helping a few beginners to make some progress and avoid mistakes. If you want to be taken seriously, learn and avoid mistakes when they are kindly pointed out to you and you certainly have many years to go before you reach my level. Just do an Internet search for me.
