What is it?
Found by a friend in her garden in cygnet, AR Australia
We are relatively certain this is some species of Tachinid Fly, but sadly, we cannot find a species match on the awesome Geocities Tachinid Page. All Tachinid Flies have larvae that are internal parasites on insects, especially caterpillars, beetles, true bugs, grasshoppers and stick insects.

A new set of images of this lovely Tachinid or Bristle Fly has allowed us to clean up this previous unidentified posting.
Update: January 25, 2014
Some recent comments on this posting by John Morgan have caused us to question the possibility that this might NOT be Amphibolia vidua. The black markings on the white abdominal area on this fly appear to be different than the 2009 Bristle Fly posting we created and the 2010 Bristle Fly posting we created that we have identified as Amphibolia vidua. Does this represent individual variation, a different subspecies, a different species or a completely different genus? We cannot say for certain. Perhaps an expert in Tachinid Flies will be able to sort this out. We are still awaiting John Morgan’s photograph for comparison.
Update: December 15, 2014
After an extensive exchange with Marlies, we are now relatively confident that this Tachinid is Formosia speciosa.
