Syrphid fly

Thank you Bug Eric for the ID

Thanks for the correction, Eric! Syrphid was another guess I had but didn't mention because i couldn't find a similar one at the time.
Luis, sorry for any confusion. I wasn't sure that it was a Thick-headed Fly. I still have a lot of learning to do!

Syrphid, actually, on the order of Pseudodoros or Ocyptamus for genus.

Thank you María dB.
Now with an Id thanks to Forest Dragon.

Great spotting!

HI Luis, this is a great wasp mimic! It's actually a species of Fly. It might be a Thick-headed Fly, Family Conopidae.
Here is Subfamily Conopinae from North America (on Bugguide). You can see the similarities:
