I'm keying out a small metallic Calliphorid and am stuck at one couplet:
Is the middle of the proepisternal depression bare or setose in this fly?

EDIT: Identified by Dr. Terry Whitworth; subject title changed to species name

Looks setose to me! :)

Thanks, next step:

Is this a Lucilia sp.?
Using Whitworth 2006: it has these character states:
1] Basal section of stem vein bare above
2] Middle of proepisternal depression setose, body shining metallic blue green
3] Thorax and abdomen shining green, blue or bronze; lower calypter bare above .. Lucilia

Then:
1] Subcostal sclerite on venter of wing with pubescence only (no wiry black setulae)
2] Palpi orange
3] 2 postsutural acrostichal setae
4] Basicosta yellow or orange
.......... coeruleviridis southern, reaching Maryland
...........clavia. as far north as North Carolina

I'm hundreds of Kms north of Maryland and probably 1000 Km north of North Carolina
