Non so quanto sia possibile la determinazione senza una foto degli ultimi segmenti addominali, ma ve la propongo lo stesso :D

I.elegans o I.pumilio?

Fotografata a fine settembre 2011 sulle sponde del fiume Olona.

Ciao Mattia,
la differente dimensione degli pterostigmi, più grande quello delle ali anteriori e più piccolo quello sulle posteriori, ben visibile dalla tua foto, mi fa propendere senz'altro per maschio di Ischnura pumilio (Charpentier 1825) ♂ - Coenagrionidae
