So I did, and I found lots. I just hope I've got them sorted out.
First the Virginia Ctenucha (Ctenucha virginica). This morning I saw many, many of these moths in the far field, as well as another, similar moth with bright yellow antennae that I haven't found an identity for. A couple of days ago I photographed what I thought might be one, but discovered on closer inspection that it is most likely the Yellow-collared Scape moth (Cisseps fulvicollis), another that Bev mentioned.
She also mentioned the Toothed Somberwing (Euclidea cuspidea) as a moth around in good numbers. It's a pretty little brown moth, too generic for a newby like me to take in. But after photographing the Yellow-collared Scape (and the hairy flower scarab I posted about yesterday) I turned around and saw a pretty little brown moth resting in the grass, and snapped a picture. Later inspection revealed that it was a Toothed Somberwing!
Finally, here's a butterfly common around here that posed for me as it warmed its wings in the sun.
