Is it just
megacephala that gather and lurk like this, or do other
Chrysomya do it too? I've seen gatherings like this in Central Australia, of metallic green flies that I assumed were
Chrysomya, on twigs and grass stalks by dung (horse) or a carcass (snake) but do not know what species and didn't have a good enough camera to get a photo at the time.

At my observations it is typical for any Chrysomya, but for bright enough illustration we need a common species like Ch.megacephala or Ch.albiceps.
It may be also intra-species conglomeration as in:

2 - Ch.albiceps, 1 - Ch.megacephala
I think that idea of such a gathering is: after laying egg(s) or larva(e) fameles wait for another eggs maturing, males wait to copulate with females. Why the hell should they to fly out?

Chrysomyia megacephala is, in my experience, strongly attracted to stinky (in their opinion: nice smelling) odours. It could also have to do with honeydew, but I don't see any signs of feeding, so that seems less likely.
