Attracted to light. I have this one in my files as #5244
Herpetogramma fluctuosalis but the PM lines suggest to me that it is #5279
Herpetogramma theseusalis instead. Alma Solis in her article referenced
on this BugGuide page mentions as distinctive feature of the species the forewing's PM line being "straight between M2 and costa" as it is on my moth. I rule out as an alternative ID the very similar looking #5278
Herpetogramma centrostrigalis that does not yet have a BugGuide page and is documented in MPG with a photo by Alma Solis. In her article she lists its forewing length to be "15mm or longer", considerably longer than what I measured for my moth.
