Kicking the ball off with two from last year.
Eupeodes latifasciatus 26th July 2008 on Clematis flammula, hopefully correct and one I haven't had this year that I know of.
Sericomyia silentis (female) 27th October 2008 on Ivy. I have had both male and female this year but last year was the first time I saw it.
