Flesh Fly

Sarcophaga bullata, a member of the family Sarcophagidae, are robust, medium-sized flies, typically 10-14 mm in length. They are characterized by a greyish thorax with three distinct black longitudinal stripes and a chequered, grey and black abdomen. Unlike many other fly species, Sarcophaga bullata is larviparous, meaning females deposit live larvae rather than eggs directly onto suitable substrates such as carrion, decaying meat, or excrement. Larval development, encompassing three instars, is rapid, typically completed within 3-10 days, depending on temperature and nutrient availability. Pupation occurs in the soil, with the pupal stage lasting from 10-14 days.

Flesh flies are strong fliers and are readily attracted to decaying organic matter, particularly carrion and feces, which serve as oviposition sites. Both males and females are opportunistic feeders, consuming a range of liquid diets, including nectar, sap, and exudates from decaying matter. They exhibit a keen sense of olfaction, enabling them to locate suitable substrates for larval deposition over considerable distances. Flight activity is often observed during warmer periods of the day, exhibiting a direct and purposeful flight pattern. Adults can be found resting on vegetation or walls near food sources.
