Sexual dimorphism

I'll agree with Graphomya maculata as an ID for this fly - It is a fairly distinctive species with its chequred black and white appearance as it feeds on umbels in mid-summer. One thing about this species is that it is sexually dimorphic, males and females look different. This is a female with the grey and white pattern - males have the white replaced with a bronzy-orange colour which makes one think they are a different species altogether.
