Here is a photo I took today. Went to Buguide. It was identified as a conopidae, species unknown. Posably physoconops, or physocephala.
Thanks so much for sending us your photo of a Thick Headed Fly. WE are linking to the BugGuide information page that states: “The adults are usually found on flowers. Food Larvae are endoparasites, chiefly of adult bumblebees and wasps. Adults take nectar.“
