Found this moth on my house, took this picture then noticed something on it that seemed to be eating into it’s side. I destroyed the thing and the moth few up to the ceiling where it is now. My question is what is the thing?

Tersa Sphinx with parasite

Dear Jill,
We suspect this might be a Dipteran parasite, perhaps a Tachinid Fly, on this Tersa Sphinx.  It is possible the infestation occurred while this moth was still a caterpillar.  We are currently searching unsuccessfully, for evidence of Tachinid Flies using Sphinx Moths as hosts.  The Moth Photographers Group has a nice parasite page.
