May be I have the solution.

The monted specimen of Battus loadamas copanae

http://butterfliesofamerica.com/imag...DHJ97461_i.htm

comes from the following original site

http://janzen.sas.upenn.edu/Wadults/...otj=DHJ97461.j

where it is named Battus ingenuus - female (the males should have a white dorsal body).

What a mess!!

Awaiting for your kind eventual comments, thanks a lot to everybody.
