Dear Steve,

    (Ah, Doug, you beat me to it!!)
     I agree with Doug.  Your moth is very likely a tropical import.  
Where exactly did you catch it, and I don't me locality.  Was it 
outside at lights, inside somewhere, outside at flowers?  I had a 
student bring me one of these here in Georgia, only to find out later 
that he had caught it inside his house!!  The next day, upon request 
from me, he brought me an exuvia from a bunch of bananas.  There are 
a couple of different ctenuchines that show up in the U.S. 
periodically shipped in on bananas (apparently these species are 
quite resistant to any treatments the bananas are put through).  I 
know of several different people who have caught these species.
