John, I made an error above: I meant to type that Pollenia atramentaria and leclercqiana are not possible for the species in the photos that you link.

further, I have no problem with labelling the following photo as Pollenia cf pediculata
https://bugguide....iew/902340

the second photo does not show enough details to exclude rudis. I can only suggest rudis group for this photo.
