Confused Eusarca Moth

Eusarca confusaria, male specimen

This moth is very abundant in overgrown former farm fields outside Chicago. It’s a relatively large critter, at least an inch across, and they fly up by the dozens when I’m walking through the underbrush. They don’t fly far – and I cannot figure how this seemingly “showy” behavior benefits this moth, survival-wise.
