almost 2", This moth is native to Europe. It was first introduced to Canada as a biocontrol agent in the early 1960s, to help combat toadflax.
I was weeding a lot of toadflax in a huge shrub bed today and found a few of these caterpillars in the mulch. It was my first time seeing them. I couldn't believe how bright the yellow was, especially while photographing them, it was almost hard to focus.
