The larval habitats of the various subfamilies can be summarised as follows: In the Heleomyzinae and Heteromyzinae the larvae mainly feed on rotting organic matter and can be found in carrion, excrement, mushrooms, bracket fungi, animal burrows, nests of birds, etc. The larvae of the Suilliinae have chiefly been found in mushrooms and bracket fungi. The adults are often found near the larval habitats, e.g. in woodland areas, but also in caves and in or near nests of birds and mammal burrows.
