I'm sorry , I can understand French language but I'm not able to write in a correct French.
I saw your beautiful photo of a larva of Chrysopa formosa Brauer, 1850 (I'm monitoring all the faunistical data about Italian Neuropterida for my web page on this topic) and I'm writeing to you only because it seem to me that no other in the Forum has sent you the name of that insect.
