Caterpillars?????? HELP!!!!?

Question

So....I have caterpillars! Well
I think that they are caterpillars...but they are smoothe not hairy. They are large worms, they are on my vining clamatis. They are leaving large roundish poops all over the porch. I have pulled 30 of them off of the stems of my flowers so far. They slightly vary in color but they are spotted greenish, some have a pink tint, some have a grey tint, some have brown tint, tan, red, etc.....they are clearly all the same worm. I am wondering what kind they are? I know there are tons of different kinds, but if anyone has any idea, or where I could look at some pictures on the net to identify them...also curious what they turn in to....moth, butterfly etc..If anyone has any information that would be helpful please let me know. Thanks so much!!

Answer 1

Probably some sort of swallow tail, but without a pic I can't say for certain. Here are some sites I've used to identify caterpillars. They've helped me.
