Migrant hoverfly?

The hoverfly Scaeva pyrastri is thought to be migrant in Ireland, so this female has come a long way. (The justification for it being a migrant is based on the late appearance of this species in Ireland.)


She was exploring the various flowers in my garden and I noticed her taking special interest in (and subsequently ovipositing on) those with aphids:



A quick check of the references revealed that Scaeva pyrastri is, indeed, predatory on aphids, so I'll try to get some shots of the larva in the next week or so.
