Subject: What is this?
Geographic location of the bug: Oxfordshire, UK
Time: 06:11 PM EDT
Your letter to the bugman: My friend’s son found this wee fella today (4th September 2021) near a boggy marsh in rural Oxfordshire, UK. We have no idea what it might be and wondered if you could help?
How you want your letter signed: Sonja
This sure looks like a Horse Fly larva to us, and we have received numerous reports this summer of Dark Giant Horse Flies from the UK here, and here, so it makes sense that this is the larva of a Dark Giant Horse Fly.
