Case of the Week 379

This case just came through my lab - alive and wrigglin'! It was removed from the scalp from 60-year-old woman. No travel history was provided.  Identification? The images and video are courtesy of Emily F.

Awesome! Is this dermatobium hominis? Bot fly is one of my favorite beasties!

There we go again: another case of myasis. Truthfully they always make me scratch my head. Finally, after some searches, I lucked out: the beast has such a striking resemblance to a previous case posted by Dr. Pritt, and more than that, she had put arrows to point out the three slightly curved slits.
I have nothing to add but agree with the first respondent: Dermatobia hominis.

This appears to be a third instar larvae of Dermatobia hominis. This is apparent by the presence of backward facing spines on the anterior portion of the larva and the lack of them on the posterior 3 segments, as well as the morphology of the spiracles, which appear to be merged and bear gently curving slits.

Dermatobia hominis.

Had one of these a few years back on a traveler to Aruba.
