Bee Fly on California Aster -- genus Poecilognathus?

This is a striking little fly (Diptera) on a new flower of California Aster (Corethrogyne filaginifolia, Asteraceae) in the woods on a rainy day yesterday. It has a clear wings and a remarkably long curved proboscis. I believe it is a atypical Bee Fly in the family Bombyliidae, maybe genus Poecilognathus or Neacreotrichus in the tribe Phthiriinae -- compare this photo. HFDF! (San Marcos Pass, 18 September 2025)
