Pines around?
Are pine trees nearby? Medetera bistriata eats things that eat pines and is common along the Gulf Coast. M. apicalis eats things at eat elms (and other hardwoods) but has not been recorded south of North Carolina and Tennessee.

Leg ratio
One of the characters used to distinguish species is the ratio of lengths of first and second tarsomeres of hind leg. What do you think that ratio is?

I enlarged the RAW file. The definition between tarsus & tree is still low. Measuring relative distances between what appears to be the "knuckles," the tarsomeres are ~equal. The 1st section may be a hair shorter.

As for pins,my 3-acre yard is ~1/3 pines. I think I may have a photo of one of these on a pine. I may have deleted,thinking it wasn't the one I was looking for :(

Definitely a fly
I wonder if this is a pale-legged form of Medetera apicalis, caught in transit so it isn't perched like a woodpecker.
