If ever a caterpillar could be considered beautiful, I think this Cecropia moth specimen would qualify.
When young, cecropia caterpillars are black and bristly; later they are orange; next they turn greenish; this is their final color phase.
Soon this one will spin a cocoon attached to a twig in which it will overwinter as a pupa.
This one was feeding voraciously on steeplebush. It didn't seem to mind having its picture taken.
