I'm leaving the name as I stated it before I knew what this moth was,
because I nailed it! Its real name is Enyo lugubris, and that means
"dead leaf moth." Folks also refer to it as a Mournful Sphinx
Bill Oehlke identified it for me. Thanks Bill! He has a
wonderful web site full of everything you want to know about
I tried to scoot the moth off of my finger and onto the wall for better (ok,
easier) photos, but it flew away.
A few days after I found the one I'm holding asleep on my Cassia, I
saw another sipping nectar just after dark.
