    This one is a different genus to your recent upload [ http://www.bowerbird.org.au/observations/46008 ] - this one lacking the right-angle bend of Sc vein, thus here meeting the costa at an acute angle. The long ovipositor is found in Facilina and Osa, but the face not being depressed from antennae to mouth rules out the former. Good chance it is O. commoni by what I can see but not fully confident.

    Thanks for the ID Tony, I have changed the title of this one, but will leave the other as Diptera sp.KH09 for now. Can you tell me anything about the other one? Is it another of the Pyrgotidae?
