Hi @MichaelMulvaney . I considered Rhagadolyra magnicornis but rejected it because I thought the pedicel on the antennae was different on the specimens I looked at (on iNaturalist). This one has short orange pedicels and the specimens on iNat had long brown ones. Is it a difference between sexes? The interesting thing was that I saw several of these flies (at least 8) and they all had short and orange pedicels. I also felt that the colouration of the abdomen was not quite right but I was most likely mistaken.

Could it be a Sapromyza sp.? It is possible that some of the flies identifies as Sapromyza sp. could be Rhagadolyra magnicornis and vice versa. All this assuming the pedicel shape and colour is significant.

Colour is a little difficult re image identification (and reliability) as colour can be greatly influenced by how an image is captured - I find Naturalist can be a good starting point but the galleries of Atlas of Living Australia are good for a final check - particularly if verified specimens are included. The colours in your images are similar to many of those on ALA. also the pattern of black on the abdomen and legs, hairs on the body and wing venation are a good match for Rhagadolyra.
