unknown caterpillar
 

This may be off-topic - but I found no better place to post it.

Some two months ago, I was in Guatemala, near to the border with
Honduras, and
took photographs of a very large and spiny caterpillar. I have put the
pictures on my Website:

and

It must have been about four inches long. Our local guide said it
might be poisonous, and, from the look of it, the spines certainly did
look impressive.
I do not know much about tropical insects, but I can't help wondering
what kind of butterfly or moth the caterpillar may have become by now.
It must be well-known, since I found pictures of it on the Web, but
always without the name or other info.

Does anyone know the name of this insect?

Thanks in advance,
Roger Van Loon.
