Tiny Snail And Bee Mimic

I think this is the tiniest snail I have ever seen. It's on a hip after the deluge. I haven't been able to identify it. 

Another hoverfly first for me. I'm pretty sure it is a bumblebee plumehorn as I can just see plumes on its antennae. This is the only bee mimic that has them.

Happy International Dog Day to all dogs and doggy people.

PS Just seen on Twitter that Sericomya superbiens, the furry peat bee mimic hoverfly also has plumes on its antennae.
