Author's notes

I think that's an enlarged sub-scutellum I'm seeing below and behind the third division of the thorax (scutellum) and obscuring the haltere. This, according to my "Field guide to Insects in Australia" by Paul Zborowski and Ross Storey, is characteristic of family Tachinidae. The fly also has interesting looking mouthparts and stands very upright on long legs.

Hi Max. Yes, you have correctly identified this as a tachinid fly based on the subscutellum. The haltere is actually obscured by the calypters - a fold at the base of the wing. I managed to track down a reference that gives descriptions of the Australian tachinids in the Dexiinae subfamily (it's listed in the species notes I posted) and am confident that your fly is Senostoma punctipenne. One of the defining features is the thickened, dark r-m vein in the wing. We've seen lots of this species recently here in Wonboyn feeding on Leptospermum lanigerum flowers.

Hi Paul, Wow! great to have you on the job. I had a look at the Senostoma punctipenne listing in species and noticed a sighting of mine from Feb 2007 which Kim has listed, just below it, as Senostoma sp. The image has a reasonable wing detail and the fly has a highly patterned abdomen. Thought you might be interested in looking at it while you have your Senostoma resources assembled. The fly was perched on the mud brick wall in our porch.

Hi Max. I’ll look through the descriptions of the other Senostoma species in the Barraclough paper to see if your earlier tachinid can be confidently placed to the species level from that shot. No promises, but I’ll give it a shot!
