I am in the pacific northwest US and i have noticed a black moth with bright red markings...?

It is about an inch across in wingspan, with a fuzzy black body and bright red stripes on black wings. They are very prolific in this area, and I am visiting Seattle for the next few months, so I am curious because I have never seen this insect in other parts of the US... Please help, I have googled and I can't find any info at all online... I figured someone out there might kno something... thanks (-;
