Helophilus trivittatus
A large and distinctive hoverfly. My wife and I came across several H. trivittatus flying in a recently flooded ditch at Bevercotes Pit Wood in July 2006 and then found more at Penny Pasture Common. H. trivittatus is noticably yellow at first glance and similarly marked to other Helophilus species.
