This is not Sarcophagidae. Probably Muscidae.
... but can you explain, please?
Hi, there are several species of Flesh Fly and you are quite correct that they cannot be taken to species level from a photograph.
I have attached a link which gives some very good images of Flesh Flies
Incidentally there is no need to put the sp. at the end Sarcophaga, this appears to be an outdated practise.
