House-fly (Mesembrina meridiana)
This is a large fly which is quite distinctive because of the brown colouring at the top of the wings, It is pretty well black all over otherwise.
Like most flies their life cycle is pretty unpleasant when viewed through human eyes. It lays its eggs in dung and the larvae then participate in the ongoing recycling of material turning cow and horse dung back in to soil. That may make Mesembrina meridiana a bit of a dirty character but it does a vital job in the cycle of life so spare some time to take a look at it. I think it strangely attractive!
