Silkmoth caterpillar (Callosamia?) - Callosamia angulifera

Silkmoth caterpillar (Callosamia?) - Callosamia angulifera
Just outside of Comer, Oglethorpe County, Georgia, USA
August 16, 2007
Size: 5 cm long
This caterpillar is a Callosamia species, possibly a Tulip-tree moth (Callosamia angulifera.) However, it lacked any black dots on the body. I don't know whether this is due to its being a particular instar, individual variation, or some other factor. When I found it, the caterpillar was clinging to a Virginia Creeper vine, but I didn't see it eating (and I suspect he/she may have fallen from one of trees overhead.)

I'm inclined to agree with your notion of C. angulifera
The larva looks to be a final 5th instar ("Adult larva"). It is also a very pale "mint blue-green" with a well developed yellowish lateral stripe typical of angulifera (usu. not characteristic of promethia).

The caterpillar in these pic's looks like any other C. angulifera larvae I have encountered or reared.

The fact that it's on the ground is also a bit helpful. Unlike promethia, angulifera larvae will often wander to the ground and spin their cocoons among the leaf litter.
