Sphinx - Syssphinx hubbardi

Sphinx - Syssphinx hubbardi
Tucson, Pima County, Arizona, USA
October 11, 2006
Size: ~40-50mm
Found in the bed of my P-up. My pic doesn't do it justice. The lateral scale-like structures were bright silver. Could it be a kind of Citheronia? Assuming I'm in the correct family to begin with?

Sphinx is not the right family
but Citheronia is in the right family, Saturniidae. But we would think it's the wrong genus. More likely Sphingicampa. We're not sure how to choose among the species in that genus. See if you can choose between hubbardi and raspa. They all seem to feed on members of the pea family.

 
Guess I'd
have to go with Hubbardi. The lateral "silvers" are flattened in hubbardi (as with my specimen) while raspa's are more cylindrical, but then you know how much I know about IDing moths and c-pillars! Thanks for the help.

 
Thanks
for the information. Your comment proves I've learned just enough about moths and c-pillars to be dangerous - hoping the next step is clarity!

 
We have them in the guide under
Syssphinx, but no gorgeous images such as these yet! We're leaning towards S. hubbardi. And you?

 
Just
visited Walsh's website and looked at both larvae of both species. Looks like hubbardi to me - did you get the images from Walsh's website, they look similar. My pickup sits under a small mesquite tree next to the house. Knowing that's one of their foodplants I'm going out right now and see if I can find any of its siblings!
