Massive hornworm, side close-up - Pachylia ficus

Massive hornworm, side close-up - Pachylia ficus
McAllen, Hidalgo County, Texas, USA
October 24, 2006
Cannot find this one in the Guide, or on Bill Oehlke's site, and my copy of Wagner is at work. Our housekeeper found this beast in our backyard, saying it had fallen out of the trees nearby as she took out the trash. So, no host plant to narrow the possibilities; our backyard includes Live Oak, Texas Sugarberry, and Texas Ebony among others.

Moved
Moved from Sphinx Moths.

How massive was it?
80mm long? 100mm? 120mm? Longer?

 
maybe longer?
I did not have a ruler at the time, but it was clearly longer, and thicker, than my index finger. I am now measuring my finger at 100 mm long and 20 thick (3.5 and 0.75 inches).

I am now at the office and looking at Wagner. Still not seeing a match. Erynnyis ello comes closest, but this worm differs from that one in several conspicuous ways...

Pachylia ficus
It does look like Pachylia ficus to me.
