My son and I would like to know what this is. We found it in our garage, it is about 3-4 inches long. We have never seen anything like it. We live in Carrington North Dakota, and we found this in mid september.

Leafy Spurge Hawkmoth Caterpillar

Dear science project,
This stunning caterpillar is a Leafy Spurge Hawkmoth Caterpillar, a Eurasian species.  According to Bill Oehlke’s Sphingidae of the Americas website:  “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, Minnesota and Oregon. The moth was also introduced from Europe into Ontario, Canada, and then into Alberta where specimens are occasionally still taken.
