Tatting and Crafting in my little corner of the world.
Ooh, it looks like you have been visited by a Zebra Swallowtail (Protographium marcellus) butterfly. Wikipedia describes these beautiful butterflies as "closely associated with pawpaws, and are rarely found far from these trees. The Zebra Swallowtail does poorly in developed areas, and prefers intact habitats."It is quite a compliment to your meditation garden to receive such a shy, breathtaking visitor!
And your other pretty visitor is a Pipevine Swallowtail!
