It's that big hoverfly with the white saddle
This is Volucella pelluscens . It's a hoverfly and it's one that you, me and the person with no natural history knowledge at all can safely identify, because it is large and has a body coloured and patterned like a Giant Panda - all you need to do is master the Latin name to score extra brownie points. The garden MV is being hogged by Tree-lichen Beauties and Jersey Tigers at the moment. Who could have predicted that a few years ago? I'm still hopeful of a screaming rarity coming my way, but in the meantime have to make do with these recent colonists.
