Your letter to the bugman: Encountered this beauty on a sidewalk today. Wings appear hollow … is it just illusion?

Dear Chris,
This is an Achemon Sphinx, and you may read more about it on Sphingidae of the Americas. The markings on the wings and the camera angle have created the illusion that the forewings are rolled, but they are actually quite flat.
