12 - Calliphoridae .- Chrysomya sp.

10 and 11 - Sarcophagidae

7,8 and 9 - Tachinidae

4,5 and 6 - all Calliphoridae - Chrysomya spp.

1 - a crazy Syrphidae

2 - seems an Ulidiidae...

This one is a calliphorid of the sub-family Mesembrinellinae (I would need a specimen to get to genus):

I only know them because they have a subscutellum, rather like a tachinid's, and they confused me for a while - until I tried them in the MCAD volume 1 family keys :D

Hmm, where is the link for the numbered photos? I just see the normal ones, listed by family.

Well, Peter has migrated the photos into the families sets. ;)

I am not convinced that these are calliphorids, I think they could equally be tachinids:

Genera such as Leschenaultia look similar to this fly but this is absolutely NOT an identification (best I would say is "possibly Leschenaultia" ) - there are too many unknowns and I'd need specimens. Even with specimens it would be very hard with lots of uncertainty ... but if you have specimens then I will try them sometime in the next few years, as I learn more :D

hmm.. maybe. But I don't see any strong subscutellum, but specially the bristles are very weak.
Maybe a interrogation point for this specimen...

Not calliphorids and indeed tachinids. As for Mesembrinellinae, I prefer to lump all species in the genus Mesembrinella. The group is quite distinctive and rather homogenous, and I see no reason to treat the various subgroups (still not well defined) as valid genera.

The three photos of Sarcophagidae are all females of the genus Oxysarcodexia.
