Banded sphinx moth caterpillar

I would guess between 4th and 5th instar? There is very few information about that. I just learned that Fasciatus is the most variable caterpillar of all Sphingidae!

Thanks again Dominik! Is this the 3rd or 4th instar do you think?

Quite a variable guy throughout the several instars:

Thanks Jacob!
Thank you too Sergio! I'm not home for another 2 days but I have a couple of hours to kill & a ton of photos to upload so I thought I would make a start! It's good to be back!

Glad to have you here again, Karen.

Awesome Sphinx!
