Yes, the female has a white beard and the body is paler in color (being gray, with the apex of the large ovipositor shiny black). The wings of the male have a large brown spot that covers most of the middle third of the wing, while the female has nearly entirely clear wing, with just a faint brown shadow in the middle third.

Some males of Proctacanthus coquillettii have whitish beards. The intensity of the yellowish-orange color hairs in your male fly seems unusual, and most males have these hairs a much paler yellow color or even white.
