Royal Moth - Syssphinx albolineata

Royal Moth - Syssphinx albolineata
Sabal Palm Sanctuary, Cameron County, Texas, USA
April 18, 2012
Size: 4.5 cm
I found this Syssphinx caterpillar feeding on Tepeguaje at Sabal Palm Sanctuary yesterday. Would anyone happen to know the species? We have had several S. albolineata flying around lately. Thank you for the help.

Moved from Syssphinx heiligbrodti.

Ed Knudson, (Texas Lepidoptera Survey), determined this a late instar Syssphinx bicolor - Honey Locust Moth - Hodges #7709.
Thanks!

 
As this was the final instar
As this was the final instar I decided to go ahead and let it pupate. As I suspected, a S. albolineata emerged last night (7-17-2012). I've posted a photograph.

 
Skeptical
I'm not convinced this is S. bicolor, all of the images I've found have little resemblance. After visually comparing pictures of each species I'm still leaning toward S. albolineata but am by no means an expert. That said, I'd rather it be left in the genus than assigned to a species which it may not be, maybe someone will come along and know for certain.

If you'd prefer to Frass it, that's okay too.

 
Did he mention his reasoning?
Did he mention his reasoning? I'd like to know how to separate these for future reference.

Syssphinx heiligbrodti - Hodges #7710
Moved from ID Request.

Syssphinx hubbardi is from central and western TX

 
Thank you
How do you tell Syssphinx hubbardi from S. albolineata?

 
Good question
I will check to be sure. Syssphinx hubbardi is common in South TX and S. albolineata apparently strays as an adult.
Nice photo!

 
We have had a number of adult
We have had a number of adult S. albolineata here at Sabal Palm Sanctuary in recent weeks. To me the caterpillar pretty closely resembles this S. albolineata:

I did run across the photo on Bill's page
and added the link to Bug Guide. There may be several photos misplaced on Bug Guide. I will check with Mike Quinn to see if Ed Knudson identified his photo. I reared S. heiligbrodti (photo below) and it does appear different than Mike's photo placed as S. heiligbrodti. Your photo and Mike's might be S. albolineata. I will check with Ed Knudson.
