Butterfly Identification - Black near white spots? I just saw the same butterfly that the soul wrote in about...

I just saw the same butterfly that the soul wrote in about 2 weeks ago. It be on my milkweed - a small black butterfly with white spots scattered over the wing - straight unfeathered
antennae and orange pollen sacs on legs. I enjoy been studying and raising butterflies for 15 years - I own never seen one like this - live or within any book. I live in southern Ontario - did anyone respond to the original cross-question?
