Observations and comments:

Note 1:  The blue spots on an orange-gold background aren't as precisely matched to the blue and gold ocelli found in the sea hares Stylocheilus striatus and Phycohila euchlora as are the markings in some other possible mimics. But, perhaps they are close enough so that Odontoglaja sp. #1 is still deriving some benefit from the resemblance (since the sea hares are known to concentrate toxins from the cyanobacteria they eat)?
