Your letter to the bugman:  I found these caterpillars on a potted plant I had.  They have eaten almost all the leaves that I can’t remember what kind of plant it was.  I’m almost sure it was an Impatien.   I think they’re the same caterpillar but not sure.  What are they?

Tersa Sphinx Caterpillars

Dear Delia,
These appear to be the caterpillars of the Tersa Sphinx, which occurs in both green and brown forms.  Are you sure the plant was
Impatiens?  A preferred food plant for the Tersa Sphinx is Pentas, according to Sphingidae of the Americas.

Daniel,  thank you for your quick response.  You’re correct,  these were Pentas.  I just couldn’t remember what kind of plant it was
