Sex
This is Tachinidae. The eye spacing rule for Muscidae does not work well to determine sex of Tachinidae. I think this is female but I'm not sure.

Thanks
From now on, all flies are Diptera when I submit! :)

Is there a page to help distinguish Muscidae from Tachinidae?

Course of wing veins
In this fly vein M is apparently forked and the forward branch of the fork ends in the front edge of the wing distant from the wingtip. In Muscidae that vein never has an apparent fork, usually does not have a sharp curve, and does not end so far from the wingtip.

There are other differences but that is an easy one to spot.

Thank you
I've removed the link between this fly and the "other one."
