Marmalade Hoverfly (Episyrphus baleatus)

Observation - Marmalade Hoverfly (Episyrphus baleatus) - UK and Ireland. Description: Lots of these around at the moment. The 2nd photo shows a much darker specimen: Ball & Morris note that dark specimens come from larvae reared in cool conditions (so why aren't they all dark in Scotland this year?)
