I often find this species in my backyard in the summer (Albuquerque, NE, Alameda 7.5 minute quadrangle). I grow grapes there, but I usually find it on the grass or English Ivy. I've posted images of a spread female, and a live female here:

I distinguish this moth from its sympatric Neofelderia rata based on its greater wingspan, more rounded boundary between orange and black regions of its forewing, and narrow band of orange of uniform width on the leading edge of its hindwing. Such distinguishing features and images are discussed and linked, respectively, at Moths of Southeastern Arizona. Wingspans of the images linked to there are 28 mm and 21 mm for N. constans and N. rata, respectively. These dimensions and criteria are consistent with those of Powell and Opler(1), which specifies forewing lengths of 12-15 mm for constans and 10 mm for rata. The subject male's forewing is 13.1 mm.

This image is derived from a stack of 59 images with a 170 µm step taken with a Nikon 200mm F4 ED IF macro lens set to F5.6 + Nikon D300 camera, and processed with CombineZP software.
