This looks like a Tachinidae to me but the arista are basally plumose?

not bent M-vein, plumose arista, no strong bristles on abdomen.. I doubt it is Tachinidae..

It's possible but you really need to check for a subscutellum to be sure - it could still be a sarcophagid :)

I wasn't sure whether there was a hidden bend - the angle of the wing could be confusing :)

well, at least there is not a strong bent in m vein. But also as you know there are not much tachinidae with plumose arista!

Yeah, unlikely to be a tachinid, unless you have one with a straight median vein, but that is still possible (eg. Ocytata) so it's best to just check for a subscutellum :)

Posted by jorgemotalmeida on 02-03-2011 00:44

well.. m vein not bends as I told. ;)

And I agree: it is needed to see the subscutellum, if there is, just to be sure!

I had the fly on hand so I took the pin out and got another view. Is it of any use?
Can't see a subscutellum - Sarcophagidae?
Terga overlapping sterites - Tachinidae?

No subscutellum and straight median vein would suggest Muscidae, as Jorge says. :) I was never very convinced by the sternite/tergite feature ... if it lacks meral/hypopleural bristles then it would definitely be a muscid or anthomyid :)

To put it simple, looks like a Muscidae to me, genus Lispe......
Wait for Nikita to see it, maybe he'll be able to confirm the idea... :D
Greetings

PS Graeme, I'm happy to see you have survived the 10 meter waves at Townsville,

If I am right then the hypopleuron is slightly anterior and below the spiracle, located beneath the calypters? If so then there are no bristles.

Hi Gerrard,
We only had a couple of windows broken, which was a relief. The backyard was 8 feet deep in broken branches. A lack of insects at the moment, but they will recover quickly. BTW I have a blue box full if you want it? Started on the next box.

No hypopleurals (you're correct on the position) puts this fly way out of my comfort zone ... so over to Nikita :D

I agree with Gerard. And large palpi is one of the features that we can see in Lispe genera, and in the last photo it is clear. If it was here in europe, it would be a Lispe, really.

That's great, thanks everybody.

Of course Lispe as Gerard said.
Probably female Lispe assimilis
