I have a lot of these all over my milkweeds.
Are they a problem?
I did a search and read they would overmultiply and eat 30% of a fir tree and other sites say they are only found on older milkweeds and dont even compete with monarch cats. Other sites don't say either way.
I don't know if I should let them be or not.
These are the brown and black ones.

Tussock moth cats
Never before have so few with so much promised to take away so much from so many and then laugh their asses off as the so many with so little vote for the so few with so much.

Re: Tussock moth cats
I am not that familar with those particular cats...but too many of anything is bad for the food source. If they are eating the mikweed then they are competing with the monarchs. I don't grow milkweed because of the aphids it attracts but we have lots of wild milkweed around here. Guess it is your judgement call to make. Sorry I am not much help!
