Chalcosyrphus species - Chalcosyrphus chalybeus

Chalcosyrphus species - Chalcosyrphus chalybeus
Depauw, Harrison County/Blue River Township County, Indiana, USA
July 16, 2015
Size: ~13mm body
hard to catch will guy, was sitting on my steps and thought this was a wasp, and of course when I realized it was a fly, it didn't stay around and finally later I collected it. Amazing mimic in flight pattern and first time seen for me in my state of Indiana

Moved from Chalcosyrphus.

Having a second look at this
Having a second look at this and the two species under Chalcosyrphus subgenus Chalcosyrphus are depressus, which have the wings clear on the basal half and only very slightly darkened on other half and aritatus which has a white arista. Looking at images of chalybeus, the area above the scutellum on the thoracic dorsum can appear flattened but is more extensively flattened in Chalcosyrphus, subgenus Chalcosyrphus. With the wings dark brownish black and the swollen hind femora narrowing at some distance from tip, it will be Chalcosyrphus chalybeus .... male.

Remove but no species
I was hoping to get a species on this by a Dipterist expert before it was moved from ID request. Thanks

 
A few of us are talking about
A few of us are talking about this one, no worries - Bill and I are learning towards Chalcosyrphus (Chalcosyrphus) of which there are two species (and no key for them, so it's taking me longer than usual especially as the major online reference for Diptera nomenclature and species records is down at the moment), but as it's the first we'd have here at BugGuide we're being cautious.

 
Thank you!
Appreciate the help, I thought once it was removed it was removed for good. I just didn't want to be put on the way side. What are the two species? The one in Kaufman has a reddish abdomen and this one obviously doesn't. Or is that red abdomen something to do with the different of male/female?

 
No worries! There are two or
No worries! There are two or three of us in syrphid-land that are pretty active in IDing syrphid flies, so it won't get ignored. I have to say, when I saw the flat scutellum (which tells this subgenus from subgenus Xylotomima) I was immediately very excited!

The two species in that subgenus are C. aristatus (which does appear to have a somewhat reddish abdomen in the one female specimen I've seen photos of) and C. depressus - unfortunately there appear to be very few collections of these two species, so locality data and specimen images are hard to come by!
