It looks like larva of Psychidae moth to me. They usually make cases from plant material, but some of them can as well use sand particles - for example Diplodoma or Teleporia. But I'm not a lepidopterologist, so that's only my guess

---

I think there are a few families in Tineoidea that make cases like that, but Psychidae is the most probable in my opinion too.

Thanks- began to wonder if it was a moth larvae.

I think it's larva of Psychidae, dahlica triquetrella.

Hi Brian, I made it here! I seem to recall there was an article on terrestrial caddis fies in the current edition of British Wildlife.

Cheeers!
