Historically, two subspecies were found in Ontario.  The Eastern subspecies ( persius ) appears to be extirpated from Southern Ontario.  The northern subspecies ( borealis ) is similar in appearance and is still found in Northern Ontario.  I have yet to photograph either subspecies in Ontario, so I'm using photos I obtained from the Western US.
