Selby Botanical Gardens in Sarasota has a butterfly garden with special flowers that attract these insects. On my latest visit to this lovely area, there were quite a few monarchs and several specimens as seen in this picture. I thought they were swallowtails but, upon further scrutiny, they lacked the typical extension on the lower wing. After perusing several books devoted to butterflies — their descriptions and identifications — I have not been able to definitively name this beauty. The closest I have come to naming it is either the Polydamas Swallowtail or the Ruby-spotted Swallowtail neither of which have the extending tail on the lower wing. Perhaps those who see this may be more knowledgable. Let me know what you think.
