Heteromyzidae (Sun Flies)

The Heteromyzidae (formerly Heleomyzidae) are small to largish flies usually occuring in temperate or wet forests. The most conspicuous in Tasmania, as is the case on the Australian mainland, are the stocky adult Tapeigaster flies which are often found on fungi hosts. Their larvae have been reared from a variety of mushrooms including Pleurotus, Amanita, Boletus, and Agaricus species. Austroleria extensa has also been reared from Boletus and it is assumed related genera/species follow a similar fungi-host relationship. Borboroides are small heteromyzids, resembling lesser dung flies (Sphaeroceridae), that are associated with wombats and can be found at their fresh dung – these have been appropriately coined Wombat Flies. It is possible the related, and similar looking, genus Heleomicra  is also integrally involved with large marsupial habitat and activity. Pentachaeta spp. and the introduced Prosopantrum flavifrons are attracted to faeces. While the larvae of Cairnsimyia robusta (Rhinotorinae: Rhinotorini) have been found living in the tunnels left behind by wood boring beetle larvae.

Officially, Tasmania has 27 described species from 11 genera representing over one third of the Australian fauna. The bulk found in Borboroides (7 spp.), Tapeigaster (6 spp.), and Diplogeomyza (5 spp.). Two species are introduced, Prosopantrum flavifrons and Oecothea fenestralis.
