Found in coastal environment, sandy sediment, humid and often windy. marsh plants. maybe erebidae?

I saw this interesting looking bug on the hood of my truck. I was wondering if anyone could identify it.

I found this nest on my back porch and was wondering if I could get the species identified.

Color is consistent throughout, however, the edges of the outer elytra are reddish. There is a distinct ridged area in the center of the pronotum (it appears sort of skull shaped). The pronotum is significantly reduced at the junction with the elytral base. Collected by S.D. Porter
