I often confuse these two butterflies as at first glance they seem the same. When I'm out in the field it's hard to tell them apart if they are flitting around so a quick reference point for me is to look at the tails...the Ornythion does not have yellow spots on the tail. Figured I'd post some dorsal and ventral photos to show them.

There are other differences - compare the forewing bottom row of yellow marks as well as the hindwing yellow marks - on the Ornythion they are more chevron like. Also the yellow band is a bit wider on the Ornythion.
