Fly - Leucophora

Fly - Leucophora
Hancock County, Indiana, USA
April 12, 2011
Size: 7 mm
Found this fly buzzing around at a window in the house.

The color of the face changes from a creamy white to a dark color (as seen here) depending on angle of view.

Attempted to key using MND(1) and ended at Leucophora. I have no idea if that's right or not.

Bristles and more bristles
The key to species of Leucophora wants to know
* Does the mid tibia have a bristle on anteroventral surface, mid ventral surface, or neither?
* Does the fore tibia have a robust apical posterodorsal bristle?
* Is the prealar bristle present? If so, is it at least as long as the posterior notopleural bristle, or shorter? (apparently at least as long)
* Does the notopleural callosity have several setulae? (apparently none)
* Are the antero- and postero-ventral bristles on hind femur longer than the diameter of the femur? (apparently longer)

 
Fly bristles
1) There is a ventral bristle on the mid tibiae, it appears to be on the mid ventral surface.
2)Maybe.
3)There are two alar bristles present, the anterior-most one is approximately the same length as the posterior notopleural bristle.
4)If referring to the area between and immediately above the notopleural setae, then they are absent.
5)Mostly shorter than the diameter of the femur, at least one is definitely longer. The shape of the hind femur may be distorted from drying, I'm not sure.

I can try taking additional close-ups if it may help.

 
Not sure
Keys to obtusa (assuming genus is correct) but it doens't look like one, because the Europeans at diptera.info says this one looks like obtusa:

Next closest match is L. unistriata, which also occurs in Europe and might be recognized by a European.

 
Interesting
I will have to repost over on diptera.info and see if its recognizable. (If you have the key in pdf format, please send me a copy.)

Moved tentatively
Moved from Root-Maggot Flies.

Leucophora is plausible
Leucophora has some early spring species that are out to raid the early spring bees' nests. They have a long face like your fly.

 
Thks John
Will move tentatively.
