Eristalis

Eristalis

Observation - Eristalis - UK and Ireland. Description: The abdominal colouring has confused me a bit here. The wings show loop in R4+5 and petiole beyond R1 and R2+3 junction, so fairly sure it is Eristalis. I wonder if it is a dark form of E. tenax? The fly was fairly large, unfortunately no good facial view
