I think Zophos is correct.
Take a look at this link: Coelonia fulvinotata, (Butler, 1875) Fulvous Hawk.

Panama what I have read up, they go through intars and the brown phase in the finally phase before they become pupa and then a moth.

I got a headache from going through all the names of moths!

Thank you Cascade, you beat me to it.

They go through a final phase change just before the pupae stage.

Regards.

Welldone and thanks for the info Cascade and Zophos :drunk:
I'll upload pics once this guy pupates and emerges. No I'm not going to feed it to my Ts. You don't see these guys that often anymore, not going to kill the ones I do come across shouting
He'll be set free once I got pic of the final phase.
