Amphonyx lucifer

I am pretty sure it is not Manduca rustica. I think it might be Amphonyx lucifer, formerly called Cocytius lucifer. But I am not 100% sure, you have to verify. If you look at the pictures in the links you can again see the great variability. Yours seems to be quite a fresh one with excellent markings, whereas some of the specimens are old and worn and colors partly washed out. And there is also a difference in coloring between females and males. http://www.guianensis.fr/images/sphingidae/sphinginae/sphingini/Guy%2000977-s3.jpg http://www.lepbarcoding.org/sphingidae/species.php?region=1&id=41172 http://www.flickr.com/photos/36494393@N00/398227514/ http://www.guianensis.fr/images/imagos/SAU%20371-s3.jpg And here would be Manduca rustica: http://www.silkmoths.bizland.com/mrustrus.htm
