Around july 21st we stayed in Kangasniemi.
There was a beautiful small forest lake with spaghnum mosses nearby.
Around this lake I found several Aeshna. But I’m not sure which ones.
Where I live only juncea is present so I have never seen crenata, serrata and subarctica.
I have photographs of 3 individuals (coded yellow, blue and green).
Of the most blue individual I also have a (not great) photo of the tip.
They are probably all subarctica. But I’m not sure about that.
The 3 individuals from the side:
And from the back:
Are these 3 the same species?
Which species? What do you use as a defining criterium?
I can upload larger photos if needed.
Thanks in advance
