HI,
I know maybe the Id for a dragonfly just looking pics is so hard, but maybe some expert know the Id of this yellow odonata:

It looks like Calopteryx sp. but not sure... Where did you find it? Don't forget, locality, habitat, size, date etc.

oh yes, sorry stupid of me to forgot it !
I found it in north Italy, near Pavia (about 100 meters altitude) in morning, one week ago.
it was long about 4/5 centimeters

I think it's Calopteryx sp too. I'm not familiar with the Italian species of this family For a moment I thought it was C. haemorrhoidalis but it misses the dark belt on the wings.

Calopteryx splendens, a female. Pterostigmas near to the apex of the wing;)

Which also applies to at least C. xanthostoma and C. haemorrhoidalis.;) I read that C. splendens splendens (nominate) is in fact absent in Italy. The subspecies C. splendens caprai "takes over" there. I've never seen it but the one on the photos could very well be the latter.

really thank you for the ID
The genre Calopterix is so Common in that zone, I usually see a lot of blue ones (Thought they are male of calopterix splendens or virgo)
greetings, Matteo

Er..., why not a Lestes?

Lestes crossed my mind too but the pure white pterostigma makes it Calopterix, I think.

Paul, in Lestes the wings has a narrower zone in his beginning (the peduncle) in Calopteryx not.;)

In North America, at least, Lestes spp. are called Spreadwings on account of the way they hold their wings at about 45 degrees from the body.
This is obviously a Broad-winged Damselfly Calopteryx

Nothing more different to Calopteryx than a Lestes!
