Pieter did find this huge butterfly 'part' and it seemed it has had an 'out of body experienc'... Probably something quite nasty has happened and it might have been eaten by something?! Does anyone have an idea about this? Would love to know. By the way, this is a Giant Swallowtail -Papilio cresphontes Cramer, 1777 Butterfly, one of the two largest butterflies in the USA. It's span measured 14 cm or 5½".
Underside...
What could have happened to this beautiful butterfly...?
Once it also looked like this...
