Found on path this morning. About 15mm long.
No identification made yet.
No interactions present.
This does look like a hoverfly larvae, and I can't think what else it could be, but it's not one I've seen before and doesn't seem to match any of the ones shown in Rotheray's guide to hoverfly larvae, so I'm unable to confirm it fully.
