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.

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.

Giant Blue Robber Fly

Dear Gwen,
We apologize for the delay in our response.  Daniel was out of the office for over a week spending the Thanksgiving holiday with his 90 year old mother and he did not answer any mail.  We agree that this is most likely a Giant Blue Robber Fly,
Blepharotes spendidissimus, which is one impressive predator.  Your images are awesome.  Can you provide us with any observation details from the sighting?

It stayed in the same position for days- we thought it was dead!!  Then just disappeared! Was amazing to look at though!

I have come across this little guy multiple times over the years when in the yard weeding and am curious what it is.  Any info would be appreciated.

Leather Jacket

Dear Kristen,
We believe you have encountered the larva of a Crane Fly like the ones pictured on BugGuide and again on BugGuide and you may read about them on the Missouri Department of Conservation site.  Charles Hogue in his book Insects of the Los Angeles Basin calls Crane Fly larvae Leather Jackets because of their “thick dark skin.”  Capital Regional District uses the name Leatherjacket.

Daniel,
Thank you so much for satisfying my curiosity.  I appreciate you taking the time to email me back.

Your letter to the bugman:  I’m unsure what this is, at first I thought it was a blowfly so I swatted it and then I noticed the yellow colouring on its back and was worried it may be a bee of some sort

This is a harmless Three Lined Hoverfly,

March Flies

Dear Amy,
Based on this BugGuide image, these appear to be March Flies in the genus
Dilophus.  There are numerous images of Dilophus spinipes on goldenrod on BugGuide.

Thank you so much!   I truly appreciate your help!
