Is this a Tachinid fly? I am going on the bare arista and the bristles at the rear of the abdomen.

Is the black and white pattern on the abdomen consistent with Tachinidae?

I notice the leading edge of the wing seems to have tiny spines on it; Heleomyzids have those, don't they? But the wing venation doesn't seem right for Heleomyzidae.
