both of those resemble Pollenia pediculata as well. Pollenia pediculata is smaller than the rest of the rudis group. I measure females consitently between 7 and 7.2mm and males between 6 and 7mm. I have no problem with labelling them Pollenia cf pediculata. None of the others are known to have a closed cell, id est, vagabunda, labialis, griseotomentosa, angustigena, and rudis are always open that we know of anyway. However, all of the remaining species are much larger than pediculata with the exception of griseotomentosa. rudis and angustigena are consistently 9-10 mm, sometimes 8mm. Pollenia amentaria and leclercqiana are not possible for the species in the photos that you link. These species most resemble pediculata.

if you collect one with a petiole, then please let me know.
