Flesh flies (family Sarcophagidae) are large, robust flies with a distinctive gray and black checkerboard pattern on the abdomen and red compound eyes. Unlike most flies, flesh flies are larviparous — females deposit live first-instar larvae directly onto suitable substrates rather than laying eggs. This gives their offspring an immediate head start in development. Flesh flies are attracted to meat, carrion, garbage, feces, and open wounds. Several Arizona species are parasitoids of other insects, including grasshoppers and beetles, making them ecologically important. However, they are also significant pests in food-handling environments and can cause wound myiasis in livestock and, rarely, in humans. Their large size and bold patterning make them easy to identify. In Arizona's warm climate, they are active for most of the year and can develop from larva to adult in as little as two weeks.
