Large, brown-faced syrphid  - Palpada mexicana

Large, brown-faced syrphid - Palpada mexicana
San Joaquin Marsh, Irvine, Orange County, California, USA
September 18, 2007
I have on file a duo of somewhat similar syrphids known as "Unidentified Hover Fly #1" and you-guessed-it. Well, there are far better photos for this one, and I hope that encourages ID to species.

(Written later 12-24-08) Martin Hauser IDed a couple of my posts as Palpada mexicana, and I'm certain this is the same insect.

Check out dimidiata
I know here in the Midwest, we're seeing a lot of E. dimidiata now (http://bugguide.net/node/view/9137). A helpful resource for this part of the country is the Syrphidae of Ontario site (http://tinyurl.com/2ujk4j), and some species might be in your area as well. The species pages are really good!

 
Dimidiata
Thanks for giving some direction to my search. Thorax on mine seems very different, i.e. more brown and hairy.

 
That Syrphidae of Ontario sit
That Syrphidae of Ontario site is outstanding! Thanks for the link. Ron you got to check it out!

 
Thanks to both.
The Ontario site does have great info. I have a candidate now: E. cryptarum, but will have to check further. (Range, etc.)

I do hope someday that someon
I do hope someday that someone stumbles on bugguide that is syrphid fly expert and also a bee fly expert especially for those Villas!

 
I doubt that photos will be sufficient
to get to species in many Eristalis , though Gerard Pennard has helped (still, often inconclusive; I have one in E. arbustorum that may belong somewhere else.)
As for Villa , this seems to be even more difficult. Few Villa are sufficiently distinct (fulviana ; lumped lateralis Say complex of species; possibly agrippina ) to ID per photo.
I do see a possibility: there are some Villa in the literature for which you could look in a specific place, and at the cited season.
Example: Villa chromolepida Cole, a fly (~6mm) with iridescent golden green scales and hyaline wings; I missed it this year.

 
Good info, as always.
I wasn't aware of the Villa situation, but have been very pleased at how bee flies now move fairly quickly to genus.

At least one of Hartmut's posts looks similar to mine:

Differences include shading in the wings on his, enlarged femur on rear legs in mine.

 
You're preaching to the choir, Tom.
And for that, you've earned a big "Amen!"
