This is Poly isn't she just beautiful*sigh stares dreamily* Sorry She is a Polyphemus Moth for more info on her see my journal here>>>[link]
Polyphemus Moth is one of our biggest moths, growing up to a 5 1/2 inch wingspan. [link] Properly Antheraea polyphemus, this giant of a moth is named after the legendary Cyclops of the same name from Homer's Odyssey. (Remember - the fierce one-eyed giant who lived in a cave and tended sheep and ate straying sailors?) These large moths are found in the Puget Sound area, though they are not terribly common; in fact, they're nearly extinct in areas with lots of street lights. When you only have a week to mate and lay your eggs, wasting time circling a light (and making a tempting banquet for bats) is not healthy! [link]
