Wahoooooo! I found the Monarch caterpillar a few days ago, and went back to check on it, and found this!! Just doing my part to maintain the butterfly population :-D
What plant is it attached to?
I planted some annual asclepias last year, and they re-seeded like mad this spring...I kept a few, and voila, here's my monarch friend.
I also planted 2 perennial Asclepia tuberosa 'Gay Buttlerflies' just a week ago.
