Your letter to the bugman:  I photographed these flies as they visited flowers at the Tucson Botanical Gardens in Tucson, Arizona.  I think that they may be Mexican Cactus Flies; and I was hoping that you could confirm that.  Of course, you may use the photos if so desired.
How you want your letter signed:  Stephen Nelson

Mexican Cactus Fly

Dear Stephen,
This is indeed a Mexican Cactus Fly,
Copestylum mexicanum.  Though the Mexican Cactus Fly is a member of the Hover Fly family Syrphidae, it does not resemble most other members of the family that look like bees and wasps as protective mimicry.
