It looks like a salt marsh moth caterpillar to me - they become beautiful moths, so congrats!!
I got a funny picture of one's face one time -

They also liked my Sweet White Clover. Very attractive adult moth, too! One of the Tigers, I believe.

Thanks ladies! Yay!!! The plant suggestions you all provided has earned a visitor to my garden. Although it's a moth, I love that something is liking the BF plants. Hope I get a real butterfly cat soon!

I went out earlier this morning and found a total of 4 of these moth cats!!!

Thanks Sherry and Susan for answering my post :)

Where are you located in Cen Tx? I'm in New Braunfels, and my garden is overflowing with pipevine and BST cats. I'd be glad to share if you have any host plants and live close enough. I planted lots of Rue to accommodate both the GST and BST cats, and so far have only seen the blacks.

Beautiful!
