Leucoma candida (杨雪毒蛾).
Recent weather has been cooler (far from cold) and damp, and while days of dragonflies and butterflies seem to be ending but I am seeing moths now in greater numbers and varieties.
In my youth on Vancouver Island it was not hard to white satin moths (leucoma salicis) out and about in the Autumn. At first I thought that is what I was seeing here, though closer examination revealed a slightly different (and both glossier and smaller) species.
