Cylindromyia (female) ... not easy to identify from photos but I will jump in with an educated guess that it is C.auriceps  Based on the hind tibial pv, crossed apicals and strong median discals ... but these can be tricky so it is always best to catch plenty and have males and females to key through

I think so - it is just the terminalia bent under but both males and females have some kind of similar apparatus so it is usually easier to sex Cylindromyia from he size of the pulvilli C.auriceps is probably the commonest Cylindromyia spp. in the south ... in my experience anyway.

I think Chris is right. If we could get a pic of the dusting pattern on the thorax, we can exclude scapularis (which is pretty rare) Theo |

I'd make that C.auriceps - the key branches on the middle longitudinal stripes - for auriceps/arator they are distinct and seperate but for scapularis/hermonensis they are merged with the broader outer stripes
