Your letter to the bugman: This guy reminds me of the hawk moths that frequent our petunias! But he’s not exactly like the ones on your page. What is he! He’s about 1.5 inches long.

Dear Robin,
There are several different species of Tiger Swallowtails and they all have similar looking caterpillars. South Dakota is included in the BugGuide data for sightings of the Eastern Tiger Swallowtail. Its coloration indicates this Eastern Tiger Swallowtail Caterpillar is prepupal.
