Welcome, Saint, any friend of an insect is a friend of mine.
I had looked at this last night and my first impression was the same as Klipspringer, but wanted to look further before posting. I STRONGLY suspect she is much more of an "expert",
as I am merely an avid (rabid)
fan of insects.
I have a Caterpillar ID book that broadly identifies caterpillars according to physical characteristics, and Tussock Moth caterpillars are known for their striking tufts of hair (tussocks), so that is the obvious first choice.
It's also important to keep in mind that caterpillars transition through up to 5 developmental stages (instars) between molts and shedding of their skins that can result in strikingly different appearances (change of colors, growth of "hair"/tufts, etc) for the exact same species, complicating the ID process.
"
While the exact number of species belonging to the Erebinae is not known, the subfamily is estimated to include around 10,000 species…" So if, (when),
you figure out which one it is, be sure and give us an update here.
