The first one is - Scathophaga stercoraria, I'd say.
The second is an anthomyiid, however, - possibly Pegomyia, but I wouldn't put money on it!

Thanks Tony. Checked a reference I have and it states that S. stercoraria usually breeds in fresh ungulate dung. I live in a small city and the fly was caught in my surburban garden!:(
That's a pretty Anthomyiid, different from the non-descript black specimen I posted a while back that generated the comment "Something near ... or another goddamned genus in this goddamned family":p

S. stercoraria is often seen on dog muck. I guess you have some of that :)

The anthomyiid does indeed look exactly like the 'old world' Rumex miners (Pegomya solennis and P. bicolor).
