Thanks you very much for your reply, John and Nini ! :D:)

I done meanwhile more research about this Fly, I have found this key about Lucilia here (page 41).
The head with the whitish orbits almost touching should fit better for Lucilia caesar ? according to the figures ? (but I could easily be wrong ?)

Also I noticed in this subject of Lucilia illustris : https://diptera.info/forum/viewthread.php?thread_id=52556 could also be more likely Lucilia caesar when I compare the shape of the cercus with Lucilia illustris. The eyes would also fit
