A Halysidota sp.
It's a Tussock Moth. But I'm afraid that's as much help as I can be.

 
Halysidota harrisii
I'd say there is a statistically significant chance that this is the Sycamore Tussock moth. Along the Devils River (where the moth was encountered) the dominant tree species is American sycamore. From my house I can see dozens of large adult Sycamores and hundreds of saplings and starts. There is nothing for tesselaris to eat here--according to the dietary list on BugGuide for tesselaris, this far west in this area there are no alder, ash, birch, elm, hazel, hickory, poplar, tulip tree, or willow. There might be Hill Country walnut in the general area, but none that I'm aware of for miles around. We do have a scrubby post oak in the area, but I imagine that the "oak" on this list refers to the white oaks or other of the big eastern oaks.
