Chrysiridia rhipheus, or Urania ripheas, is a day-flying moth of the family Uraniidae. It is considered one of the most impressive and appealing-looking lepidopterans.
It's very colourful, though the iridescent parts of the wings do not have pigment; rather the colors originate from optical interference.
The background photo was taken by MyMy Butterfly at the Westview Mausoleum in Atlanta, Georgia.
These specimen are incased in a 9"x9" frame.
