genus/species of papilionid?

Since I don't know how to or if I can post a photograph, here is the
link to a site with a picture of a beautiful looking larva:

Does anyone know any information about this creature photographed by
my brother in Oxapampa, Peru? The orange antennae are attached to the
real head.  The prominence above the head has false eyes.  Please send
me e-mail if you can.  Thanks.
