We have been obsessed with trying to identify your magnificent black fly with a golden head, but alas, we have had no luck. The Bioimages website Diptera page is rather difficult to search for images and it proved fruitless. www.gwydir.cemon.co.uk is a nice website with numerous photos of flies, but again, your distinctive fly is not represented. We believe this is a Flower Fly or Hover Fly in the family Syrphidae. We would not rule out a Bee Fly in the family Bombyliidae, or it may even be in some other family. We have finally decided to post your photos and request assistance from our readership and we will also be writing to Eric Eaton to see if he can at least provide the family.
We believe the third photo you submitted is of a different species since the wing pattern is different.
Eric Eaton provides an identification
Yes, this is definitely a large tachinid fly, Family Tachinidae, maybe Tachinia grossa. The third image is of the backside of a different fly, and that one is a flower fly (Syrphidae), specifically Volucella pellucens.
