Screw-worm fly research. Worker weighing screw-worm fly (Cochliomyia hominivorax) eggs at a breeding program used to study and help control this parasitic insect. The adult flies lay their eggs in the open wounds of warm-blooded animals,including humans. The larvae (maggots) then use their sharp mandibles to dig into and eat away the living tissue. This can severely damage or even kill the host. After 3-7 days,the larvae fall to the ground to pupate.
