Chrysomyia Chrys·o·my·ia (krĭs'ə-mī'ə, -yə)
A genus of flies that includes species that cause myiasis in humans.
The screw-worm flies (chrysomyia macellaria) are among the most common and important of these (Fig. 25).
Osborn quotes a number of detailed accounts of the attacks of the chrysomyia on man.
Screw worms (fig. 4) are the maggots of a fly (chrysomyia macellaria), so called from their fancied resemblance to a screw.
