Sphaerophoria, male?
According to the pictures and comments in this site http://www.gardensafari.net/english/picpages/sphaerophoria_scripta.htm this would be a male because of the shape of the abdomen. I would like to have some confirmation of this. Also I think that perhaps this photo http://bugguide.net/node/view/7036is a female Sphaerophoria, and I would need confirmation on this too.

 
A male, yes
Indeed, a male.

Sphaerophoria
It is a species of Sphaerophoria, one of the genera with aphid feeding larvae. Adult males of most species can only be identified on the basis of their genitalia, females can often not be associated with a species without accompanying males.

Looks like a flower fly
Looks like a flower fly (family Syrphidae). I believe mydas flies are generally very large, over an inch long, and have distinct antennae.
