Syrphidae in VC85

A remarkable graphic from NBN which suggests that no Syrphidae of any species have ever been recorded at Loch Leven (??!!)

This surely can't even be possible, can it?

Certainly identifies a large hole where >100 species ought to be

Dalgety Bay also has zero species. Hopefully an upload to NBN from HRS, or even iRecord, could clear up that picture somewhat.
