Need help identifying an insect.

[Firewallx]

Can anyone help me identify what kind of caterpillar this is? I can't seem to find it on my own.

It kinda looks like a horn worm but I’m not sure what the red thing is on it. Hold on, someone will be along that might be able to tell better than I.

Thank you for answering. It can't be a hornworm as it is missing the side marks. But yeah, that was my first reaction, too.

 

[Lindasjackson]

I have no idea then.

Yeah looks like a tomatoe hornworm to me?

Ok I got an answer from a guy at the Caterpillar Lab. I wish to share the answer here. He said it is an Abbott's Sphinx moth caterpillar in its fourth instar. I googled it and there's a site with a matching picture.
He said when it molts into the fifth instar, it will be a very good snake mimic.

Very interesting! Are they native to where you are?

 

[Chameleoking]

Yep. Abbott's Sphinx moth. Definitely

From what I have found, they can be found in quite a few states / provinces in North America.
