Co·chli·o·my·ia hom·i·ni'v·o·rax

the screw-worm fly, a species that is a serious pest of livestock from Mexico to Argentina and is the primary cause of myiasis in the western hemisphere; attracted by fresh blood, it deposits eggs on wounds, tick bites, or intact moist areas of the body, and the larvae invade living tissues, causing severe myiasis and often death; it is known to attack humans, especially in the nose, although wounds, eyes, and other body openings have also been attacked.
