First I would like to say We in Costa Rica.... do not have "Atlas Moth"/ "Attacus Atlas".....Could this be a Rothschildia cincta...? bayucca?

I would be nice if fhtenbolscher change the ID for the correct one....I posted a Rothschildia triloba and people is telling me is an "Atlas Moth" ,Attacus atlas....And this is a Costa Rican Club....?????

I guess that Caño Negro is lowland area so it is not Orizaba and neither Lebeau and Aurota (which is not in Costa Rica, but South America). Usually you need a real expert for IDing Saturniidae. Since I am not really one, I am a little bit on the edge ;-)..., but I think it is OK with Triloba.

I agree that it is one of the Rothschildia moths. Unsure which. I was leaning towards one of the Rothschildia aurota.

The Atlas moth is actually an Asian species but I found another photo online of a Costa Rican specimen

Impressive! It's actually a moth from the family saturniidae. The closest I could find was Cincta rothschildia so I think it is a close relative -
