Phigalia
This one is most likely denticulata based on the "tooth" on the PM line at vein M1. See my comments here. So far, that characteristic is panning out to be diagnostic. I'd like to be able to examine a few hundred genetically identified specimens to have a better sample size for solidifying the characteristic, but from those I've seen thus far, it looks good.

Well, heck! I thought I had this one right due to the green coloration, the relatively straight trajectory of the PM line and the fact that it had been 2 weeks since I'd seen the last denticulata. P. strigataria flies later here in west TN and this moth looked pretty fresh.

I'll always bow to your expertise. I need to inform Bob P. because this image is being used on MPG's strigataria page.

Update
I've been reviewing some of the old Phigalia IDs and I think you were correct with this being strigataria. The tiny "tooth" on your specimen's M1 vein is less than half the length of the larger tooth beside it, which seems to be the deciding quality for 'reduced' when using this feature - at least so far in the specimens I've gotten my hands on over the years.

So now the olivaceous color and weak transverse lines make more sense on this beauty.
