Hello,
Is it Rhamphina pedemontana? This species seems rather variable, at least in terms of color, but the proboscis puzzles me, comparing it with pinned specimens (2 here and 1 at tachinidae.eu) : shouldn't its curve make it point forwards?
Thanks in advance.

The proboscis of some American Tachinidae curves in a different direction in dried specimens.

Yes, the proboscis is flexible to some degree.
Moreover, you have two species of Rhamphina, need to check that.

The way I understand Herting (1971), is that the haustellum is flexible in pedemontana and rigid in rectirostris. Anyhow, this is Rh. pedemontana.
