Unnamed spotting

Sorry, but like I mentioned in an earlier comment, these are the only shots I have. I was doing other work and stopped what I was doing to shoot these, and due to the fact that the caterpillar was not stretched out, I neglected to gain an image of the entire organism. As for the host plant, I have absolutely no idea. One bright point is I have learned my lesson and now shoot as many angles as possible. :-)

I need a shot of the entire caterpillar to speak with confidence, but based upon configuration of the head capsule and what can be seen of the body, C. illioneus is indeed a very good possibility. What kind of plant was it found on, please?

OK, Aaron, you have now 2 options: a) you believe the old and wise or b) you wait for Keith for final ID. If I were you I would prefer b)...

Unfortunately, these are my only images of this caterpillar. :-( I'm looking back at the 2007 trip photos and am wondering why I didn't shoot more of each subject. It's ridiculous how few angles I have of many organisms.

Do you have any other shot from the middle of the caterpillar (even a bad one)?? I would need this one to definitely exclude Caligo telamonius menus, the other possible candidate.

Is some kind of dragon caterpillar it may be from the Opsiphanes sp.

Interesting creature. I like your second picture.

Thanks. This was one hefty cat!

Very cool :)

Third photo is fantastic, Aaron.
