They are large moths with a wingspan of 4 1/2 inches. They are a lovely light green color, with eyespots on their hindwings and long, fairy-like tails. I am sure that as caterpillars, they sustain many creatures as food, although as adults they have no mouthparts, and never taste food themselves. But when I see them as exquisite sprites, I cannot help but wonder if their presence might serve to ignite our senses of what it truly means to be alive! Thank you Luna.
