Bopth pics taken Yesterday at 1:1 uncropped. Assume #1 is Sarcophaga carnaria but is #2 just a small one of the same species ?
They were both sitting on a tree stump next to each other.

Well, they're all sarcophagids but I wouldn't be so rash as to give them a name ;) The top one might be
Sarcophaga carnaria, "
sensu latu" but you need to see the male genitalia to be sure because there are about 6 very similar species :) The second one does look a bit different but I'd need to see the specimen to be able to say for sure - scale is a bit hard to judge from close-up photos and they all look very similar from the top :) Sarcophagids are worth catching because in my experience you can find quite a few species just by collecting as many different-sized flies as you can on a site.

Well, pic 1 is a female Sarcophaga, so very difficult to tell the species (if possible at all).
Size is not of real importance, although anything < 7 mm. is bound to be NOT carnaria.

Thanks for the info :)- just to be useful the smaller fly works out at 7.8mm body length, larger one about 12.4mm body length.

I agree with Theo, that the smallest S. variegata or S. carnaria catched by me in nature is only 7 mm long. But I have raised once a group of nearly 20 on 1 earthworm. They finished the whole within good 2 hours. Being afraid for starvation they pupated and came to life again as 5-mm-flies, smaller than I have ever seen. Jan H.C.Velterop.

The second fly has only 3 post-DC, forget ID. Jan H.C.Velterop.
