The long story of my encounter with this caterpillar is here, but what will it become?

This is the caterpillar of a moth of a family called "Limacodidae", most probably genus Parasa. While the caterpillar to my eyes is beautiful, the moth itself is a rather inconspicuous insect...

Erwin

Thank you Erwin, other responders off-list also suggest the family Limacodidae and suggest a type of saddleback moth, I've no pictures of the adult moth but at least one person suggested the next one I find I keep and nuture to maturity in case it's not yet documented. I have read that there are many speices that are not yet offically named.

Some useful notes for those finding this thread.

The larvae are green and fairly smooth many have tubercles with stinging (urticating) hairs and may have bright warning colours. The sting can be quite potent causing severe pain. If you come in contact with the stinging hairs, the experience is much like a bee sting.

To remove the hairs quickly, place a piece of cellophane tape (or whatever kind of tape you have at hand) over the spot and remove it quickly - the hairs will stick to the tape. The sooner you do this, the less effect the sting will have.

A solution of 2–2.5% hydrocortisone cream applied to the affected area may help relieve the symptoms.

A more serious consequence is urticating hair in the eyes. In this case it is necessary to immediately wash the eye thoroughly with copious amounts of cold water and see an ophthalmologist.

Urticating hair is the primary defense mechanism used by tarantulas and lepidopteran caterpillars. This term refers to the barbed hairs that cover the dorsal and posterior surface of the abdomen. Many tarantula species will frequently kick hairs off their abdomens, directing them toward potential attackers. These hairs can embed themselves in the other animal's skin or eyes, thus inducing physical irritation. Or create a dust cloud that affects the lungs if breathed in. Urtica is Latin for "nettle".
