Today’s word of the day is luna moth, which is described by The Century Dictionary as “the most beautiful of North American insects, of a light-green color relieved by luniform eye-spots and by a broad purplish-brown or liliaceous anterior border.” There are many photos of this beautiful insect on the entry’s Flickr page. The caterpillar is kind of amazing, too, though you need to be sure that’s what you have!
