Found monarch larvae eating bindweed (Blue Vine Milkweed)

[biwa]

Thanks for posting that photo applestar, I'm glad to see it's doing so well. Now that I've identified it, I've found tons of little blue vine milkweed plants in my lawn; I've been trying to transplant them to better spots.

The monarch larvae I saw on the blue vine milkweed last year were big and plump. Some looked big enough to start doing the metamorphosis thing. So the blue vine milkweed clearly doesn't stunt their growth.
