Taxonomy

Family: Muscidae

Subfamily: Muscinae

Genus: Australophyra Malloch 1923

Species: rostrata (Robineau-Desvoidy 1830)

 

The first- and second-instar larvae were described by O'Flynn & Moorhouse (1980).

Biology

Commonly known as the black carrion fly, this fly is commonly observed around carcasses, particularly during the advanced stages of decomposition (Fuller, 1934). Its seasonality in Canberra was documented by Fuller (1934).  She found that it is common year round, but most abundant from October to December, perhaps hibernating during Autumn. As a tertiary carrion fly, it generally infests carcasses at a late stage of decomposition when they are desiccated. The larvae, which may be predacious on other maggots, are rarely observed in carrion while primary invaders, such as calliphorids, are still present (Fuller, 1934). Australophyra rostrata has a minor role as a tertiary sheep fly.

Larval development of this fly has been investigated by Dadour et al. (2001) and O'Flynn (1983).

Distribution

This fly is very common in Australia. It has been recorded in all states, however, is most abundant in southern Australia, and relatively rare in the tropical northern areas.
