Flesh Flies are in the family Sarcophagidae (from Greek σάρκο sarco- flesh, φάγε phage = eating; the same roots as the word Sarcophagus. They differ from most flies in that they are ovoviviparous, opportunistically depositing hatched or hatching maggots instead of eggs on carrion,dung, decaying material, or open wounds of mammals, hence their common name. Some flesh fly larvae are internal parasites of other insects such as Orthoptera. Adults mostly feed on fluids from animal bodies, nectar, sweet foods, fluids from animal waste and other organic substances. Juveniles need protein to develop and may be laid on carrion, dung or sweet plant foods, including fruit, nuts, and artificial foodstuffs.
