I think that is a screw worm larva of Cochliomyia hominivorax

Myasis caused by the New World screw worm Cochliomyia hominivorax.

I finally got around to listening to our mentor via TWIP:
http://www.microbeworld.org/podcasts/this-week-in-parasitism/archives/1730-twip-75
Recommended. I was pleased that the TWIP host, Vincent Racaniello, was as hopeless at these identifications as I am (I'm a bioinformatician). Co-host Dickson Despommier was equal parts parasite-raconteur-par-excellance and condescending know-it-all. Dr. Pritt handled herself with aplomb. --bks

Based on the spiracular pattern, I'm thinking blowfly...

Definitely a case of myasis. Upon further consultation with the PHIL/DPDX, I wonder if the larva in question was Cochliomya hominovorax or a Phaenicia species (Blow fly). Please shed a light.

I had no idea what myiasis was before I read the comments for this post. Gross, but interesting!
