One morning during our vacation in Vermont, one of these was on our patio screen. Isn't it beautiful? It's about four inches across. It's a Luna moth. It looks just like leaves with dewdrops. Unfortunately, although they aren't yet endangered, their population is decreasing rapidly. See, they find each other by glowing in the moonlight, and with all the artificial light from lamp posts, parking lot lights and other outdoor security lights as well as the glow from windows, they're being led astray. How sad. I feel very lucky to have seen one and shown it to my children. It was just so beautiful. The picture doesn't do it justice. Gypsy moths and Tent Caterpillar moths, on the other hand, should be fed to each other.
