Helina evecta

This fly has a pale brown or blue abdomen with dark spots. It has notable dark veins on its wings. 

It cannot be reliably separated from H. annosa without detailed examination. The setae on the underside of the hind femur are a key feature. In H. evecta these are restricted to the apical third and long (more than the width of the femur). In H. annosa they extend along the length of the femur and are shorter (up to the width of the femur).
