the hairs should be characteristic but you are in Portugal, so it is better to double check Calliphoridae. I agree with Lucilia ampullacea but maybe my opinion doesn't matter. Some people want opinions from experts only.

I have two female specimens so i can help with a female too if you find one. I love Calliphoridae and Lucilia are very pretty flies to me.

I hope that you have a pleasant day.
