Large Bumble Fly? - Copestylum mexicanum

Large Bumble Fly? - Copestylum mexicanum
Sunnyvale, Santa Clara County, California, USA
September 17, 2009
It really seemed like a male carpenter bee staking out its area. It's wings moved very quickly creating a noticeable buzz, and it challenged anything that came too close.

Notice the size of the eyes! Most of the shots used a flash, making an interesting, if not helpful effect on the eyes...

It seems to have some syrphid-like qualities to me, such as the tucked and pointed abdomen. I have seen a "Mexican Cactus Fly" posted that I think was close to this one in appearance.

Large Hover Fly (Syrphidae)
Strongly reminding of the Cactus Mexican Fly (Copestylum mexicanum), although compound eyes are distinctly redder here. Either just a feature of the Northern populations, or else a close, but different species of Copestylum not yet on BG.
May large black flies are easily mistaken for Carpenter Bees. Southern European Horse Fly Dasyrhamphis ater is another striking example.

 
Thanks, Richard!
Good to hear from you! The eyes did not seem quite so red when the flash was not being used. I like the effect, but it is deceptive. I think this is Copestylum mexicanum!

 
Your ID's solid, Mac.
You da man for shootin' them in the air! I've never got one coming at me.

 
Thanks, Ron!
I like finding Ivy along a stretch of fence because the flies are limited in how deep they can go while harvesting the Ivy. It makes for some interesting shots sometimes!
