What are these caterpillars, what are they going to turn into, why do they clump like this, and why does one (lower right) appear to have white things on it?

We believe these Caterpillars are in the Brush Footed Butterfly family Nymphalidae, and the caterpillar in question appears to have been parasitized by a Chalcid or Braconid Wasp. We will contact Keith Wolfe to see if he can identify the caterpillars more specifically.
Keith Wolfe provides a correction
Nope, these are immature moths, the scoli (spines) being much too long for any Neotropical nymphalid.
After Keith Wolfe’s correction, we are now speculating that they are relatives of Buck Moths in the subfamily Hemileucinae and we will see if Bill Oehlke can provide any information.
