I have heavy milkweed competition going in my milkweed patch.
A fuzzy black and orange caterpillar is competing in eating all the milkweed leaves with my dozen Monarch caterpillars.
Should I remove them??
I can send a photo.
I found your caterpillar at monarchwatch.org... it is described as
Tussock Moth - Feeding by these hairy caterpillars is extreme. Large numbers of caterpillars are commonly found on a single plant which they completely defoliate.
So I guess relocate them to a place where you aren't wanting Monarchs I guess!
