This one (sorry about the bad photo, but it was very small) I thought might be a Platystomatid (Signal) Fly but in viewing the Lauxaniid gallery I can see (to my untrained eye) some similarities to Homoneura sp. A few of these flies were moving in amongst some citrus in pots in my garden at The Gap, a suburb of Brisbane, Queensland, Australia. It was about 2mm long, settling on leaves, not very fast flier. robertwhyte attached the following image:  [16.43Kb] Edited by robertwhyte on 27-01-2008 01:01 Robert Whyte, Save Our Waterways Now (SOWN) http://www.saveourwaterwaysnow.com.au |

Lauxaniidae. Steve Gaimari will tell more.  |

sure looks like a lauxaniid, in an unfocused gestaldt kind of way! Probably a species of Homoneura - this kind of wing pattern occurs in this genus in Australia, so that's my best bet. |

This afternoon after a hot day I got a couple of shots of a couple.

Same location as the previous two shots, perhaps a little larger, about 2.5mm on a citrus (orange tree) in Brisbane, Australia.

The first one should be Homoneura, and I would not be surprised if the second one were too. At least I am certain it is a lauxaniid.

The 2nd looks to be a Lauxania sp., but let us wait for Steve Gaimari.

yes, the second species (the black one) is also Homoneura. They are really diverse in that neck of the woods! (Australia and Southeast Asia). There are a couple of other genera with all black species, but this one is certainly Homoneura. |

Thanks everyone, I must admit I thought it a little reckless and irresponsible to post the pic of the black flies here as I really did not guess they might also be lauxaniid! Lucky I was slack, it ended up in the right thread after all. Thanks again. Just to explain why the photos are so crap, I have posted a pic of myself with camera in the thread for photos of dipterologists. (Which I'm not, but maybe one day...)

you are, at least, a curious what is great! And the amateur dipterologist status can fits well. As you see you was right about your family hypothesis for these flies. It means that you know *something* about flies.  And the gallery is for amateur and curious dipterologists not just the professionals and the big experts. all are welcome. |

This one is a bit larger than the previous ones I posted here, maybe about 3mm body length, it was hovering around a Syzygium in my garden in Brisbane while I was experimenting with a Pansonic Lumix with Raynox magnifier. It landed on my hand so I was able to manoeuvre it into the sun for this pic. I was wondering it also is a Lauxaniid?

Yup - definitely a lauxaniid. This one is in the genus "Sapromyza" as it is currently (mis)understood for Australia! I may be able to get a species name on it Monday...

Yup - I thought I could get the species once I had my notes! This is Sapromyza occipitalis Malloch. Couple important characteristics - the paired blackish patches on the occiput, the legs and antennae being dark, unmarked wings, 0+3 dc with anterior seta smallest, etc. Cheers, Steve |

Hi Steve, Another pic from today with a strange hoover apparatus on the front end, of what I take to be the same fly species as above?

This has the appearance of Muscidae.
