Hi!
Photo on Finland Kokkola 27 August 2018.
Is it possible to get species for that male?
Thanks for help.

another view isn't helpful unless the cerci surstyli are visible.
The coxopleural streak is necessary in order to separate caesar, illustris and ampullacea sans genitalia. If a coxopleural streak is present and the hypopygium is smaller, then you have illustris. caesar has a very large hypopygium.
you can collect Lucilia and view them alive with a microscope.
I've attached a photo of the cerci and surstyli of caesar.
