Tibiae without dorsal preapical bristle.

Biology

The larvae of most species live in rotting wood, bracket fungi, or mushrooms, some species live in nests of birds where they feed on the blood of the nestlings (Neottiophilum), or in carrion, mainly that of larger vertebrates (Thyreophora and its allies), or in substrates rich in protein. A well-known representative of the latter group is the larva of Piophila casei (Linnaeus), a pest in a large variety of animal products such as cheese, dried fish, meat, etc. The adults are not very active fliers and are mainly found near the larval habitats for oviposition or on tree trunks and logs, possibly for mating.
