First of 2 new hoverflies in the garden

Backblip: this week, I have seen two species of hoverflies in our garden that I hadn't seen before. As this is posted as a backblip, I know that the second species will come tomorrow! I took shots from a few angles to help with identifying this beastie and, although I acknowledge all of the usual caveats about identifying hoverflies from photos and not specimens (and why would I want to kill them?), I'm as sure as I can be that this lovely bumblebee-like hoverfly, taking nectar from an oxeye daisy, is Criorhina berberina. If it is, I might have a reasonable right to feel satisfied as the larvae of this species develop in rotting wood and I have been building log pile habitats in our garden for a few years and some are now quite advanced in their state of rotten-ness. As the garden was full of these hoverflies, I am quite hopeful that they have emerged from my habitat piles. All dependent, of course, on whether I have identified it correctly! On the plus side, even if I'm wrong in my identification, it is still a new record of some other species in our garden!
