I believe this is Tachinidae.And I'm guessing Goniinae? At light, Townsville, Queensland.

Clearly a Siphonini. If I remember correctly, you have Peribaea and Ceromyia. It is not Peribaea, so it should be Ceromyia.

Thanks Theo. Got it wrong again. However it is pleasing to know that my pictures are adequate enough for you to say "It is clearly Siphonini". I've just got to keep at it I guess. What a huge array of thoracic spines.

I read that Tachininae are uncommon in Australia. If you like spines, the abdomens of New World Tachinini are impressive. Several genera are densely covered with long spines.

Hello Graeme!
your photos are beautiful ;)
What settings do you use to get such quality.

I started in macro ...
Thank you for your advice!

Hi Benoit, and thanks for the compliment. I use a Canon 5D mark ll body with either the 100mm macro or the EF-65 macro lens. The latter is for really tiny stuff. The camera is mounted to a StackShot focusing rail, which can be controlled from the computer using Helicon Remote software. The stage is a board with a car stand bolted to it and 3 LED mains powered lights for illumination. The car stand has a course thread in it which enables me to move the camera a large amount quickly, necessary when changing lens'.

I can see that the picture is difficult to pick out the various bits. I'll get somebody to hold a sheet up behind and get another shot.

Hi Graeme;

Sorry to inform you that Siphonini are one of the most simple tribes to recognize: habitus !. In doubt, look for the converging subapical scutellar bristles.
As well shown in your excellent pictures !

Just a comment Benoit. If you really want to do great insect pictures you will have to get into stacking sometime.
