Injured

This hoverfly was injured in some way, covered in dust on the path. I think it survived an attack from a bird or other predator but it is unlikely to have survived much longer after I moved on.

UPDATE: I'm pretty sure this is in fact a dark giant horsefly! They can grow up to 5cm - this one was probably 3.5-4cm. The smaller ones are bad enough - this one could take an arm off!
