Beautiful picture. Someone local can help identify whether it is a beneficial insect egg or not. Otherwise I would definitely destroy them. Chances are the insect larvae would feed on the leaves of your plant as soon as they emerge.

Thanks.

I scrapped them off this morning. Didn't want to take any chances.

A moth of some sort.

I think it is the Tussock Moth caterpillar. I felt something was crawling over my body while looking at the pics on Google.

I visually examined the plant leaf by leaf and remove all the caterpillars (about 20) - costed me 1.5 hours.

Looks like a very close match flashphoto.

Yes I think so. Doing more research, the Milkweed Tussock caterpillar can completely consume the whole plant
