What you have found is the beautiful Ceanothus silk moth, one of the largest moths in the Pacific Northwest. It is a native species and not considered a pest. The caterpillars, which are also quite beautiful, feed on plants in a wide range of botanical families (Rhamaceae is the most common). Management recommendations are to admire its beauty and let it be free. To learn more about other large moths in the PNW, check out:
