This beauty is the Hornworm of the Leafy Spurge Hawkmoth, Hyles euphorbiae, as you can see by viewing the images on Sphingidae of the Americas, and the reason this Old World species, native to Switzerland is represented there is explained on the site: “The leafy spurge hawk moth, Hyles euphorbiae (length: 2-3 cm, wingspan: 5-7 cm), was the first classical biological agent released against leafy spurge in the United States, with approval for introduction granted in 1965. Populations of this insect are present in several western states, including Montana, Idaho, North Dakota, Wyoming, Minnesota and Oregon, and now Washington (Spokane County; David Droppers; BAMONA). The moth was also introduced from Europe into Ontario, Canada, and then into Alberta where specimens are occasionally still taken.“
