Migrant Moths...Mexico...ID?

[DR. JAMES ADAMS]

Dear Bobs et al,

           Bob Russell was close.  The species is actually Urania 
fulgens, a very close relative of U. leilus, but north of the South 
American U. leilus.  Urania fulgens is found throughout 
Central America and Mexico.  (It's even been taken in the southern 
U.S. a couple of times.)  These moths move in mass periodically, and 
it sounds like this was one of those times.  The numbers mentioned do 
seem particularly impressive.
