Bee mimic on goldenrod - Eristalis flavipes

Bee mimic on goldenrod - Eristalis flavipes
Brainard Lake Recreation Area, Boulder County, Colorado, USA
August 16, 2013
Size: BL ~ 13 mm
This fly is on goldenrod at Brainard Lake, elevation about 10,500'. This bee mimic fooled me completely. It was Gene that noticed the fly eyes in the photograph. The wing venation is not readable, but it looks the most like a deer bot fly in genus Cephenemyia. Any help with its ID is most appreciated.

Moved from Narcissus Bulb Fly.

Thanks for guiding me through this procedure.

Eristalis flavipes
Eristalis flavipes.... male.

Merodon equestris has the legs and tarsi black and a re-entrant upper outer cross-vein and male hind femora broader than this and the tarsi are more expanded on Merodon than this.
Hind metatarsus is bright orange.... Eristalis flavipes.

Thanks so much for identifying this amazing bee mimic. I really appreciated your help!

Moved from Syrphid Flies.

I believe it's Merodon equestris, Lynn, but am a bit gunshy.
Here's why...

(Legs and color look a bit different, but the face and hair on eyes make me think "Merodon".)

Agree with Merodon - the flattened rather than downwards projecting face matches Merodon to my eyes. Moving to species!

Also note similar color patterns here:

ID'd by Martin; definitive ID based on hind leg morphology. So no worries on that end!

Merodon equestris
Thanks to all of you, Ron and Kelsey and Martin, for identifying this fabulous bumble bee mimic. It is greatly appreciated.

The very red hind tarsus is the give away for Eristalis flavipes, very similar to Merodon, but M equestris has always black tarsi!

Eristalis flavipes
Thanks so much for this information on how to separate these two species. Your help is much appreciated.

Merodon equestris maybe
Thanks for this suggestion, Ron. Really does look like it. What seems so strange is that exotic syrphid from Europe is such an excellent mimic of our bumble bees! Of course, Europe has its share of bumble bees, too.

Moved from Flies.

Thanks so much for identifying this mimic to family.
