Robber Flies

Huge unknown wasp looking bug
August 28, 2009
The other day I was launched into action as screams came from the kitchen. “Daddy come get this bug it’s HUGE!!!” So I did what Dads do and got it but now I would like to know what in the world it is… I’m 37 years old and lived in Arizona my entire life and have never came across anything like it. This bug was HUGE. I would have to say larger than a silver dollar. I forgot to put something like a quarter in the picture to get reference as to size but believe me… HUGE…
Thank you for your time

Hi Daddy Matt,
In the past year, both we and BugGuide have gotten several reports of this majestic Robber Fly, Archilestris magnificus, from Arizona.  Prior to that, the species was known from Mexico.  Robber Flies are predators, and they might bite humans if carelessly handled, but they would need provocation to bite.
