Hello Bugman, I believe this is a bristle fly going on the photos I’ve seen here. This is only the second of these flies I’ve ever seen here after 13 years of living in the area. It was seen in Healesville, Victoria, Australia on Nov 29th 2010, that’s just a couple of days before Summer.
The first time we posted a photo of this distinctive fly in 2007, we posted it as an unidentified Tachinid Fly. In 2009, we posted another image, still unidentified, and we eventually learned it is Amphibolia vidua and the common name Bristle Fly is used for the family Tachinidae, the Tachinid Flies. You are correct in calling your individual a Bristle Fly.
would you like some more photos for your files? I tried to put them on yesterday but they were all too big. I’m happy to email them to you if you want them.
Just to give you some more information- I’ve seen one of these flies once before here, about 5 years ago, it was very sluggish and divebombed me, and in my panic I swatted and killed it. The black shape on the rump (do flies have rumps?) was very slightly different to this one, it was a perfect heart shape. I assume they are the same type of fly and there’s just a bit of individual variation.
Thanks so much for getting back to me, your site is fantastic!
Thanks for the additional information and photos.
