Monarchs are rare visitors here, usually just passing through to a warmer or cooler climate, depending on the time of year. I was surprised to see this one Wednesday morning, cavorting on Tithonia with the Gulf Frits and Dark Swallowtails.
I always look up Monarchs to make sure my Monarch isn't a Viceroy. The double row of white spots confirmed him. Viceroys have a dark line on the hind wing to distinuish them.
