Camillidae
Camillidae is a small family of minute flies (2–3.5 mm) within the superfamily Ephydroidea. The family contains five genera, four extant and one fossil. Adults are slender, lustrous black flies with hyaline wings and distinctive bristle patterns on the head and thorax. Larval biology is poorly known, though they have been reared from bat guano and rock hyrax dung, suggesting a role in decomposing organic matter in sheltered environments.
Histiostomatoidea
Histiostomatoidea is a superfamily of mites within the suborder Astigmata (Sarcoptiformes). Members are characterized by highly modified mouthparts adapted for feeding on decomposing organic matter and associated microorganisms. The group includes families such as Histiostomatidae and Guanolichidae. Many species exhibit phoretic relationships with insects, using carriers for dispersal.
