The thing was massively huge -- at least 8 inches from wingtip to wingtip. I hurried snapped three or four pics and only one turned out. It is above.
I googled moths of the Caribbean and came up with an identification. It is an Ascalapha Odorata, or a noctuid or owlet moth.
When I read the Wikipedia article about the moth to the Lovely One, she was scared. The Lovely One is superstitious. This moth is known as the Black Witch. It is a harbinger of death in Mexico and some of the Caribbean. However the Lovely One brightened up considerably when she found out that in these islands, it is called the Money Moth, and that money will come to you. In South Texas, if the moth lands on your door and stays there for a while, it means that you will win the lottery.
I personally believe that it is bad luck to be superstitious. However I do like the concept of the Money Moth.
