while reading up to ID some SC images on BugGude, I am having my doubts about this one. Of course, being from AZ the color patterns could be entirely different from eastern populations of L. daturaphila.

It might be best to move this one back to the genus level. I don't remember anything else from AZ looking like this, but I also probably wasn't entirely familiar with the area's fauna either.

based on my collecting experiences in AZ, this is most-certainly L. daturaphila (=trilinea). They were quite common at middle and lower elevations, especially on Datura.
