Have you ever seen a clear winged butterfly? Yep, they do exist... We found these in an off road butterfly park about an hour out of Capetown

UPDATE: 8/5/05 The Oregon Zoo has a butterfly exhibit with these butterflies in it! They call them "Costa Rica Clearwings" It's wonderful, and well worth the extra admission to stop in and see all the butterflies. Although they were listed on the board as being there, we didn't actually SEE any of these flying around or on bushes. :( The person there said they were having some troubles with them in the exibit.
