Catapillar on my milkweed...not a Monarch!

Asked July 26, 2019, 2:36 PM EDT

Hello, Could you please help me identify this catapillar and tell me about it, as it is on several of my milkweed plants. I need to know if it is an invasive species or not. Thank you! Carmen Trettel

They are young milkweed tussock moth caterpillars. There are so many because they just hatched, but they stay together as long as possible. They will eventually eat much of your milkweed. See, or
