What's That Bug? does not endorse extermination

Mexican Robber Fly
I wrote you last year with this huge unknown insect and you
were able to id it as a Mexican Robber Fly; very rare and
only seen in Arizona and only a few times.
Well, he’s baaaack. I got one of these shots on August
26, 2008 and the second one on Sept. 01, 2008, at which time
I saw TWO of them fly away! I live in a remote desert area
bordering Cochise County, about six miles west of Benson,
Ariz., at an elevation of 4,600 feet. Love your site and use
it all the time to id bugs! Thanks for being there.
Best Regards,

Hi Carol,
Thank you so much for reporting this year’s sighting of Archilestris
magnificus (Walker).

Update: (09/07/2008)
I don’t think that robber fly is “rare” any more. I collected one in Amado, Santa Cruz County, AZ just the other day, and saw another one at the same location. I think they are probably established in Arizona now.

    We found one of these Robber Flies at our stable today, been searching all over for an identification for him! We see them often, located in benson Az, and they are often confused on fly by’s with our tarantula wasps, except their body shape is quite different if you get that good a look at them!
