What is this large white moth?

[Doug Yanega]

>We recently had 2 large (at least 2 1/2 inches long each) moths mate, then
>lay very organized eggs on our white garage. The moths were both all white
>with black circles. Some of the circles were all black, but some of the
>other circles were not filled in. The eggs are  khaki- colored, and they
>were laid all in a row, with some other smaller rows on top of each other.
>I still don't know why the moths laid the eggs with no apparent foodstuffs
>available. If anyone could help me identify the moth, I'd be very
>appreciative. I've tried all my insect/ moth and butterfly guides, but
>can't find anything even close. I live in a suburb of Cleveland, Ohio.
>Thanks, Chris Gurnick.
 
Try Hypercompe (=Ecpantheria) scribonia, plate 16 in Covell's field guide
to eastern moths.
